Frequently Asked Questions


Where is my data stored? Is it safe? Can I get it out again?

Your library (reference data, notes, folders, labels) is stored safely in our database. The data is stored redundantly on multiple servers and we keep continuous backups in a completely different data center. You can export your library in common file formats (RIS and BibTeX) for use with other software. In addition, you can download all your data in machine readable JSON format.

Your PDF files and all other files in your library are stored on Google Drive, Google's cloud storage service. Using the Google Drive client for Mac and Windows you can keep a backup of all your files on your local hard disk.

Where can I run Paperpile? Does it run on Firefox/Safari?

Paperpile is fully supported on Chrome for Mac OS X, Windows, Linux and Chrome OS. It also known to run on the open-source Chromium browser. Since Paperpile uses advanced features of the Chrome platform, it is not available on other browsers.

What about my tablet?

You can read your PDFs through the Google Drive app that is available in the iOS App Store and in the Android Play Store.

Use the "Star" feature to compile your reading list. Starred papers will show up in a dedicated folder in your Google Drive so that you can easily find them.

Dedicated mobile apps are planned. Subscribe to our or follow us on Twitter for announcements.

I'm missing feature X, will you add it?

Please be patient, Paperpile has just started and we will add features continuously. Some of the most frequently requested features that are on our roadmap: Shared folders (added 1/2014, see blog post), full-text PDF search, PDF annotations, Word plugin.

I'm having problems running Paperpile or found a bug, what do I do?

If you experience problems first read our guides and our troubleshooting page, which cover the most common issues. Also try to reload the Paperpile tab and/or restart Chrome; this can help solve some temporary problems.

If you think you have found a bug please contact


Using Paperpile

Can I filter my papers by multiple criteria?

Yes. Use the Shift key when clicking on a folder or label to add additional filters.

How does Paperpile search my library? Can I choose a specific field to search?

Paperpile searches within most textual data fields from your papers including title, abstract, author names, journal, publication year, notes, and identifiers (DOI, PMID, etc.). Searching within a specific field is not currently supported, but you can filter your library by a specific author, year or journal name by clicking on the author / journal / year from an item in your library.


File syncing

Where are my files stored?

If you import a file to Paperpile a local copy will be stored within Chrome. This allows you to quickly view your files without re-downloading them every time. If you enable syncing to Google Drive, your files will be stored in the folder 'Paperpile' in your Google Drive space. Once synced, your files can be accessed when you run Paperpile on different computers or for reading on a mobile device.

Can I change how files are organized in Google Drive?

Files are organized in subfolders sorted alphabetically by the first author's last name. At the moment it is not possible to customize this structure (many users wish to use the same folders / labels created in Paperpile). This limitation is mainly for technical reasons, and we hope to offer this highly requested feature in the future.

Tip: Starred papers are organized in a special folder, which is useful for example to create a reading list for quick access on your mobile device.

I already have my PDFs in Google Drive, can I import them directly from there?

No. For privacy reasons Paperpile can only access files that were uploaded by Paperpile and are stored in the Paperpile folder. So Paperpile can't access your PDFs that you already have in some other location in your Google Drive. We suggest to sync the files to your local hard drive and upload them again from there.

What can I do if my files are not synced correctly?

In most cases your files will be synced completely automatically and there is no manual action required. If you run into problems, check out our file syncing guide.


Google Docs integration

These are a few commonly asked questions about the Google Docs integration. To learn how to use the Google Docs plug-in, view our guide on Writing papers in Google Docs.

How does it work? Where are my citations stored?

When you cite an article in a Google Doc, the citation data is copied from your personal library to a separate library created just for that document. When you choose a citation style and click Paperpile > Format citations Paperpile will format the citations, create a bibliography, and re-insert the formatted text into your document.

You can seamlessly collaborate with other Paperpile users on a single document, adding citations and seeing each others' changes in real time. And because all references are stored in a central library, there's no need to worry about keeping everyone's personal libraries in sync — it just works.

If you work with collaborators who aren't yet using Paperpile, they can still help edit the manuscript and view a document's citations: each citation and bibliography item links to a page where you can view / edit the citation.

What happens if I cite something and then my collaborator tries to format the document? Will it still work?

Yes! Any author with Paperpile can format the entire manuscript without any trouble. Since every citation is added to the same document library, all of the data required to format a document is stored with the document rather than in each user's personal library.

Paperpile does not have a citation style for my journal. What can I do?

Paperpile uses the Citation Style Language (CSL) to format citations and supports thousands of different journal styles maintained at If there is no style for a particular journal, chances are that there are identical or very similar styles you can use. To find the right style you can use "search by example" tool:

Tutorials & Guides

Getting started

First thing's first — you'll want to add some papers to your new library to learn how to organize your papers and work effectively with Paperpile. Read on for some tips on how to quickly make the most out of Paperpile.

Note: if you already have a library from Mendeley, EndNote, or other software, see our guide below on how to Import your library and PDFs.

Add papers

The first thing to do with an empty library is to fill it up with papers relevant to your work. Paperpile make this easy with three ways to find and add articles from the web:

  • Click Add papers button to search online directly from Paperpile or upload PDFs from your hard drive.

    Tip: to quickly upload PDFs, just drag and drop from your file manager into the Paperpile window.

  • Use your browser to search for articles on Google Scholar, PubMed or ArXiv and click the import buttons Import button.
  • Click the Paperpile button Paperpile toolbar button in your browser toolbar to import from hundreds of supported publishers' sites. A green arrow appears on the button when you're viewing a supported site (For an example visit

Get organized

Next, add some folders and labels to help keep things tidy. Click the New Folder button Paperpile new folder button to add a new folder. You can rearrange your folders by dragging (labels are sorted automatically).

Drag a paper into a folder using the drag handle Drag handle on the left side of the paper, or use the toolbar buttons Folders and labels toolbar buttons to organize many papers at once.

Cite, copy, paste

You can quickly copy and paste formatted citations using the copy button Copy toolbar button. Choose between copying the plain citation string, a rich-text version with abstract & links (good for emailing), or the Bibtex data for manuscript preparation.

What's next

Where to go from here? You can learn about some of Paperpile's other unique features by viewing our guides on how to Write papers in Google Docs and Sync your files with Google Drive.

But more importantly, Paperpile makes reference management easy so your next step can be to get back to doing what you do best — research!


Import your library & PDFs

Ready to make the switch? Easily import your existing reference library from most popular software directly into Paperpile — here you'll find complete instructions for migrating from Mendeley, Zotero, Papers, EndNote, Citavi, or other software. Or, just add your PDFs directly and let Paperpile organize them for you!


If your library is fully synced online: If you keep all your articles and PDFs synced in Mendeley, Paperpile can automatically import your Mendeley library and PDFs from the web with one click. Open the "Add Papers" menu, choose Import from other programs button and then follow the on-screen options.

If your library is not synced: Your Mendeley library and PDFs can still be imported with a few easy steps:

  1. Select all papers in your Mendeley library and choose File > Export.... Change the format to RIS – Research Information Systems and save to your desktop (example).

  2. Find the folder where your Mendeley PDFs are stored by right-clicking on an item with a PDF and choosing Open Folder. Navigate to the folder that holds all of your Mendeley PDFs, and keep that folder open for the next step.

  3. In Paperpile open the "Add Papers" menu, choose Upload files button and add both your exported RIS file and your entire Mendeley PDF folder to the upload dialog. Click Start upload to begin.

  4. Paperpile will import your library and attach all existing PDFs to their correct articles when possible. When the import is complete, double-check any articles marked as incomplete or duplicates to help keep your library clean.


If your Zotero library is synced online: Paperpile can automatically import your Zotero library and attachments from the web with one click. Open the "Add Papers" menu, choose Import from other programs button and then follow the on-screen options. Note: Private group libraries will not be imported when "Accept Defaults" is selected. In order to import also private group libraries click "Change Permissions" and select in "Default Group Permissions" the "Read Only" option.

If your library is not synced: Import your Zotero library and PDFs with a few simple steps:

  1. Export your Zotero library to a new folder on your desktop. Choose File > Export Library... and select RIS format with all options checked (example).

  2. In Paperpile open the "Add Papers" menu, choose Upload files button and add your exported Zotero folder to the upload dialog. Click Start upload to begin.

  3. Paperpile will import your Zotero library and attach each PDF or attachment to its correct article where possible. When import is complete, double-check any articles marked as incomplete or duplicates to help keep your library clean.


Import your Papers library and PDFs into Paperpile with just a few clicks:

  1. First, export your Papers library with the command File > Export... > Refman RIS File. Save your entire library to a file on your desktop (example).

  2. Now locate your Papers Library directory. Go to File > Preferences in the Papers menu. The location of your library will be listed in the Library tab of the Preferences window. Go to the library folder and find the Files folder within it. Keep this Files folder open for the next step.

  3. In Paperpile open the "Add Papers" menu, choose Upload button and add both your exported RIS file and your entire Files folder to the upload dialog. Click Start upload to begin.

  4. Paperpile will import your library and attach all existing PDFs to their correct articles when possible. When the import is complete, double-check any articles marked as incomplete or duplicates to help keep your library clean.


Any EndNote library, including attached PDFs, can be easily imported into Paperpile with just a few steps.

  • First, open your EndNote library and export it to your computer in XML or RIS format: click File > Export..., under output style choose "Select Another Style" (example). This will open up a new dialog; choose EndNote Export (recommended) or "RefMan Ris Export". Make sure to uncheck "export selected references" to ensure that your entire library is exported (example). Click Save to save this file to your desktop.

  • Second, find the ".Data" folder that holds your library's PDFs. For most libraries, EndNote creates a folder in the same directory as your EndNote library file. It has the same name as your library with the suffix ".Data" appended (example). Keep this folder open for the next step.

  • Back in Paperpile, open the "Add Papers" menu, choose Upload button and add both your exported XML/RIS file and the entire ".Data" folder to the upload dialog. You can add them either by dragging them onto the drop area, or by using the "Choose file(s)/Choose a folder" buttons. Once you see your RIS and folder in the list of selected filed, click Start upload to begin.

  • Paperpile will import your EndNote library and attach all existing PDFs to their correct articles when possible. When the import is complete, double-check any articles marked as incomplete or duplicates to help keep your library clean.


Citavi 5 and Citavi 6 libraries can be easily imported into Paperpile with just a few steps.

  • First, open Citavi and create a backup of your project. You will find this option in the File menu.

  • Second, locate the backup on your computer. It's a file with the file ending with ctv5bak or ctv6bak. The backup file is actually a zip file. In order to extract it, replace the Citavi file ending with zip.

  • Once, the zip file is extracted, you should see ctv5 or ctv6 files. These files can directly be uploaded to Paperpile.

  • Back in Paperpile, open the "Add Papers" menu, choose Upload button and add the extracted ctv5 or ctv6 files to the upload dialog. Click Start upload to begin.

Other reference managers

If your reference manager supports exporting to either Bibtex or RIS format, you can simply export your library to a file and import to Paperpile using the Upload button function.

If you cannot export your library to a standard file format, Paperpile may be able to extract metadata from your PDFs themselves — see below.

Unorganized PDFs

In many cases, useful reference metadata can be extracted even from a collection of unorganized PDFs. Simply drag and drop some files into the Upload button window (example) and click Start upload to begin.

Paperpile will parse each PDF and use all detectable metadata (including data fetched online from databases like PubMed) to import the article into your library. A message will be displayed for any errors or warnings encountered during the import process.

Note: if a PDF matches up exactly with an existing item in your library, Paperpile will automatically attach the PDF to that item instead of adding a duplicate entry.


Write papers in Google Docs

Paperpile's Google Docs integration is so simple that most users need no introduction — just create a new document and start writing! For those who like to be prepared, here is an overview of the main features and tips for collaborating on academic documents with Paperpile and Google Docs.

If you are having trouble with the Docs plug-in, visit the troubleshooting page for tips on how to solve the most common issues.

Inserting a citation

To insert a citation, either click the Paperpile button Google Docs Paperpile button in the toolbar or use the keyboard shortcut Shift-⌘-P (on Linux or Windows use Ctrl-Alt-P ) to open the citation window:

Google Docs Paperpile insert citation dialog

Start typing to search within your library. Paperpile will search within the title, keywords, abstract, etc. of all papers in your library, the same as when you search from the main Paperpile interface (example). Choose a result to add it to the current citation:

Google Docs citation added

To add another item just start searching again. Or, click on any of the citation tags Google Docs Paperpile citation tag to edit advanced options (see Advanced options for citations below). When you have finished creating a citation, click Add citation to add it to your document.

The citation is inserted into the Google document as a link with placeholder text, e.g. Google docs citation text. Note that this is not the final formatted citation; see below for instructions on Formatting a bibliography.

Advanced options for citations

Clicking directly on a citation tag opens up a panel with details and more advanced options:

Google Docs citation details

The upper part of the panel shows a familiar overview of the citation metadata with a link to open the item in Paperpile.

Below that are three advanced citation options:

  • Location / page numbers: choose from a range of location types (see a partial list) to use when citing a specifc page, chapter, or book from within a larger work. Example: Google Docs citation location.

  • Prefix / suffix: Add arbitrary text to be included before or after the inline citation. Examples: Google Docs citation prefix and Google Docs citation suffix.

  • Suppress author: this option causes citation styles to not display the author name within inline citations. When using a parenthetical citation style, this allows you to include just the year in parentheses. Example: Google Docs citation hide author instead of the usual Google docs citation default.

Formatting a bibliography

After adding or editing a citation, Paperpile can reformat your document and generate the bibliography with one click. Simply choose Paperpile > Format citations to proceed. (Note: you will need to give permission to the plug-in the first time you format a document. This will only happen once.)

To choose a different citation style, open the citation style window with Paperpile > Citation style...:

Bibliography style dialog

Search for the journal or publisher whose style you would like to use, and a preview will show in the bottom of the window. Click Update to update the citation style and reformat the document to see the changes.

Collaborative editing

You can edit a Paperpile-enhanced Google document with any number of collaborators, whether or not they already use Paperpile. Just click the Share button in the upper-right corner of the screen and choose who to share your document with.

If you share the document with collaborators using Paperpile, they will be able to add new citations and reformat the document without trouble (see our FAQ entry on how collaborative citations work). For anyone not using Paperpile, citations and bibliography items will link to a web-based view where you can edit or update the data for a given item.

Important: Citing a document from your personal Paperpile library will create a local copy specific to the Google Document. This copy will be updated if you update the original copy in your library. However, as soon you or someone else edits the local copy of a Google Document any subsequent changes you make to the original copy in your library will not update (and thus overwrite) the local changes. Also, changes made to the local copy by yourself or a collaborator will never propagate back to your library.

Citation styles

Paperpile supports the popular "citation style language" CSL with more then 8,000 citation styles available from We regularly update the citation styles in Paperpile so that you always get the newest styles and updates.

To change the citation style in a Google Document go to Paperpile > Citation styles and search for the name of your style.

If you can't find your style you have two options: (i) find an identical or very similar style or (ii) create your own style. In both cases you can use the citation style editor available at This free web-tool allows you to find styles and to modify existing styles to your needs.

If you have create your own CSL style, download the CSL file to your harddisk and upload it to Paperpile in Settings > Citation styles. You can then select this style in your Google document as described before.

DOIs and URLs in your citations

For most reference types Paperpile lets the citation style control how to display DOIs and URLs.

However, for print articles Paperpile does not show DOIs or URLs by default. More precisely, citations of types "Journal article" and "News article" with the field "pages" set will not include DOIs or URLs.

To override this behavior, activate the option "Always include DOI and URLs". This option will show DOIs as specified by the citation style. Note, that some citation styles don't support DOIs and this option (despite its name) cannot change that. You may need to adapt the behaviour of the citation style by editing the CSL file (see above).

You can store multiple URLs in the field "URLs". Paperpile will always use the first in citations.

Known issues

  • You can only use the Google docs plugin with the same Google account from which you signed up to Paperpile. If you have documents owned by your non-Paperpile Google Account, share and edit them with your Paperpile-linked account.


Sync your files with Google Drive

Here is some more information about how synchronization of your files to Google Drive works. Check out also the FAQs about syncing.

What you need to know about the Google Drive sync

  • Google Drive syncing is initially turned off. Enable sync by clicking on the Drive icon in the top right of the Paperpile tab.
  • Once enabled, all syncing takes place in the background and no manual action is required. The Drive icon indicates the current status of the sync process: Sync menu
  • To check if a file is synced, open the file panel by clicking the paperclip symbol File panel icon. The drive icon indicates the sync status of a file:

    File panel icon
  • The contents in Google drive always reflects your Paperpile library. Make any changes (e.g. delete or rename a file) directly in Paperpile, not in Google Drive — this is the safest way to make sure you don't see unexpected results. However, Paperpile is smart and works hard to automatically fix any inconsistencies encountered during sync.
  • Files are arranged in folders by the first letter of the first author's last name. All files are prefixed with 'Author year' of the reference they belong to (e.g. 'Crow and Kimura 1970'). The main PDF for a reference is renamed with the title, while all supplementary files maintain their original filename (plus the 'Author year' prefix).


  • The drive icon says "Sync has been disabled because of errors": Normally, if there are problems syncing your files (e.g. Google's server is temporarily overloaded), Paperpile will automatically try again and there is no action required from you. However, if a problem persists and several sync attempts fail, syncing will be disabled. Wait some time and click the icon to re-enable sync and start a new attempt.
  • One or more files did not get properly synced: If a file is not synced, click 'Start sync now' in the drive menu on the top right of the screen. That will force a re-sync of all your files. It does not re-upload any files unless necessary, so it should finish within 1-2 minutes. If the sync is still not successful, read on and try the next tip. Also keep in mind that files bigger than 20Mb are currently not synced.
  • The sync process hangs and the Drive icons keeps flashing forever: The Paperpile Chrome extension (which runs invisibly whenever Chrome is running) contains the code that actually syncs your files. Even if you reload the Paperpile application tab, it will not completely reset the file syncing. In the rare case that your sync is stuck for a long time, either restart Chrome completely or reload the extension.


Share papers with colleagues

Paperpile includes two simple yet powerful ways to share papers: share papers via link or email to quickly send articles to your colleagues, or create a shared folder to create shared lists of relevant references and PDFs with other Paperpile users.

Sharing papers via link or email

To quickly share papers, select some items from your library and click Share > Share via Link or Email in the toolbar. The following dialog will appear:

Share with a link dialog

Your papers are ready to share — just copy the unique sharing link and send it to your colleagues. Everyone with the link can view the papers online (no Paperpile account is required).

You can also enter an email address in the "Send an email" area to have Paperpile send an email on your behalf. To include a customized message or subject line, click "Add a message" below the email address field (example).

When you email a paper with Paperpile your colleagues will receive a message listing the first few items and a link to the entire set of shared papers. If available, each paper includes a link to the publisher's website and to your personal copy of the PDF in Google Drive. For more details, see the how sharing works section below.

Creating a shared folder

Sharing with a link is quick and easy, but if you want to add or remove papers from a shared collection or collaborate on a shared reference list with other Paperpile users, then a shared folder is the way to go.

Shared folders work just like regular folders in Paperpile, except that multiple users have access to the folder and can add and remove papers. Create shared folders for journal clubs, reading groups, or to collaboratively collect references for your next manuscript.

To create a shared folder, click the Paperpile new shared folder button button next to the area in the left pane. Alternatively, you can select a few items your library and choose Share > Create New Shared Folder:

Menu item to create a new shared folder

Paperpile will create a new folder and pre-populate it with your selected items (if applicable).

Message shown after creating a shared folder

Click "Manage sharing" to invite new collaborators. The following dialog will appear:

Settings dialog for a shared folder

Each shared folder gets a unique link to share — this can be shared with anyone, and provides a read-only view of the items in your folder. To give other Paperpile users the ability to add and remove items to and from your shared folder, add their email addresses to the "Invite collaborators" area.

Adding new collaborators to a shared folder

Click Save to update the folder's sharing settings. Email notifications will be sent, and your collaborators will see the shared folder the next time they open Paperpile.

List of new collaborators in a shared folder

Note: when you add collaborators to a shared folder, use the same e-mail address they use for their Paperpile account. This is usually their personal or institutional GMail address. If you add someone using a non-Paperpile email address, they will show up in the access list without name or photo (example). To fix this, remove the non-Paperpile email and add their correct address.

Working with shared folders

Anyone with access to a shared folder can do the following:

  • Manage who has access: all collaborators on a shared folder have permission to add or remove collaborators through the "Manage Sharing" dialog. The only exception is that nobody can remove the folder's owner. Since all collaborators are given equal access, be sure to only invite people who you know and trust.
  • Add or remove papers to or from a folder: add papers easily by dragging one or more selected papers onto the shared folder, or alternatively by selecting one or more papers and choosing Share > Add to Shared Folder from the toolbar. To remove papers from a shared folder, make a selection and choose Remove from Folder from the toolbar. You can remove any paper from a shared folder, including ones not added by you.
  • Add or remove subfolders: click the context menu next to a shared folder and choose Add Subfolder to add a new folder below the selected folder.
  • Copy papers to your personal library: you may often want to take an article shared by a colleague and save a copy in your own library for future reading, organization or note-taking. Paperpile makes this easy by showing three different icons for papers in a shared folder:

    •    You added this paper to the shared folder. Click the icon to view it in your library.
    •    Another user has added this paper to the shared folder, so you may add a copy to your personal library. Click the button to copy a single paper, or select one or more papers and choose Add to Library from the toolbar. Paperpile will copy the paper and any available attachments (learn how this works) to your personal Paperpile library.
    •    You have a copy of this paper in your library. Click the icon to view your copy of the paper.
  • Shown below is an example of three papers with three different states: added by you, added by another user, and added by another user with a linked copy in your library.

    Shared papers with three different states

More info: how Paperpile sharing works

For those who would like to know more about how things work behind the scenes, here are a few relevant technical details behind Paperpile's sharing functionality:

  • Items are shared with a reference, not by copying: when you share a paper, Paperpile creates a reference to your personal library item, not a copy. This means that your collaborators will always see the latest version of the paper you added, just as it looks in your personal library: if you edit the title, add a note, or upload a PDF or supplementary file, all your changes will be immediately visible to everyone. However, this also means that if you delete an item from your library, it will no longer be available to your collaborators.
  • PDFs and attachments are shared via your Google Drive: When someone clicks "View PDF" on a shared paper or copies it to his or her personal library, Paperpile will generate a read-only link to your synced Google Drive file for viewing and downloading. This works the same as if you had chosen "Share with a link" from within the Google Drive interface and shared the link with your collaborators. Note: this only works if you have enabled sync and the given attachment has been successfully synced online.
  • Anonymous file downloads are restricted: Paperpile makes it easy to collaborate on shared reading lists and send relevant articles to your colleagues, but it is your responsibility to ensure that you do not facilitate illegal distribution of copyrighted works (see below). In practice, this means that you should be careful who you invite to shared folders and with whom you share a web link. To make sure no copyrighted material is made public accidentally, shared links are excluded from search engines and anonymous downloads of PDFs and other files are tracked and restricted at a reasonable limit.

It is your responsibility to respect the intellectual property rights of the owners of any work that you organize within Paperpile. You may only share content with other users (including article PDFs, text, and supplementary files) if you have the right to do so. You can share papers if you are the copyright owner, have the copyright owner’s permission, are permitted to do so under your publishing agreement or your institution’s license agreement or under license from an Open Access database or under a Creative Commons license.

For more information, be sure to read through our terms of service before using Paperpile's sharing features.

Library proxy access

You can download PDFs with restricted access while off-campus through a proxy connection provided by your institution or library.

Select a proxy connection for your institution

Go to Settings > Proxy Access. Search for your institution or library and click Add Proxy Connection.

Proxy access configuration

Click Log in to authenticate with the proxy server using your user name and password, library token or other authentication method your institution or library uses.

You can verify that the connection works with Test connection

Add a custom proxy connection

If your institution or library is not in the list, ask your IT department or librarian for help. If your institution supports remote access via "EZProxy", they can provide you with a proxy URL, e.g.$@. Note, the "$@" is a placeholder that tells Paperpile where to put the URL that should be accessed via the proxy server.

Add this URL to the field URL, give your connection a name, e.g. "My university library" and click Add Proxy Connection. Log in and verify that the connection is working (see above).

Using library proxy connections

If Paperpile can't access a PDF, Paperpile will re-try downloading it through your proxy connection. You can configure multiple connections and activate and de-activate connections right from the main screen using the proxy connection menu on the top right:

Proxy menu

Always make sure you are logged in to your proxy. Follow the "Login page" link in the proxy menu.

Paperpile will show a warning if you have configured and activated a proxy but you are logged out.

Proxy logged out

Important notes

  • A few instutitions have configured their proxy access in a way that makes it impossible to be used by Paperpile. In particular, EZProxy servers using "Proxy by Port" configurations are not supported. This legacy configuration is not not recommended by the developers of EZproxy. We encourage institutions to update their settings to "Proxy by Hostname" to make their proxy access more accessible.
  • Your institution might use other technologies for remote access than the "EZProxy" approach described here. Most popular are "VPN connections" or direct proxy servers. All these approaches are fully supported by Paperpile but need special programs or configuration of your computer. Please ask your library or IT department for more help.
