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.
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.
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.
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.
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 email@example.com
Yes. Use the Shift key when clicking on a folder or label to add additional filters.
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.
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.
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.
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.
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.
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.
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 clickPaperpile 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.
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 uses the Citation Style Language (CSL) to format citations and supports thousands of different journal styles maintained at citationstyles.org. 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: http://editor.citationstyles.org/searchByExample

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.
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 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.
Next, add some folders and labels to help keep things tidy. Click the 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 on the left side of the paper, or use the toolbar buttons to organize many papers at once.
You can quickly copy and paste formatted citations using the copy 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.
But more importantly, Paperpile makes reference management easy so your next step can be to get back to doing what you do best — research!
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 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:
Select all papers in your Mendeley library and choose example).. Change the format to RIS – Research Information Systems and save to your desktop (
Find the folder where your Mendeley PDFs are stored by right-clicking on an item with a PDF and choosing. Navigate to the folder that holds all of your Mendeley PDFs, and keep that folder open for the next step.
In Paperpile open the "Add Papers" menu, choose and add both your exported RIS file and your entire Mendeley PDF folder to the upload dialog. Clickto begin.
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 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:
Export your Zotero library to a new folder on your desktop. Choose example).and select RIS format with all options checked (
In Paperpile open the "Add Papers" menu, choose and add your exported Zotero folder to the upload dialog. Clickto begin.
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:
First, export your Papers library with the command example).. Save your entire library to a file on your desktop (
Now locate your Papers Library directory. Go toin 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.
In Paperpile open the "Add Papers" menu, choose and add both your exported RIS file and your entire Files folder to the upload dialog. Clickto begin.
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 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 to save this file to your desktop., under output style choose "Select Another Style" (
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 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, clickto 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 themenu.
Second, locate the backup on your computer. It's a file with the file ending withor . The backup file is actually a file. In order to extract it, replace the Citavi file ending with .
Once, thefile is extracted, you should see or files. These files can directly be uploaded to Paperpile.
Back in Paperpile, open the "Add Papers" menu, choose and add the extractedor files to the upload dialog. Click to begin.
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 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.
In many cases, useful reference metadata can be extracted even from a collection of unorganized PDFs. Simply drag and drop some files into the window (example) and click 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.
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
If you are having trouble with the Docs plug-in, visit the troubleshooting page for tips on how to solve the most common issues.
To insert a citation, either click the 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:
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:
To add another item just start searching again. Or, click on any of the citation tags to edit advanced options (see Advanced options for citations below). When you have finished creating a citation, click to add it to your document.
The citation is inserted into the Google document as a link with placeholder text, e.g. . Note that this is not the final formatted citation; see below for instructions on Formatting a bibliography.
Clicking directly on a citation tag opens up a panel with details and more advanced options:
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: .
Prefix / suffix: Add arbitrary text to be included before or after the inline citation. Examples: and .
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: instead of the usual .
After adding or editing a citation, Paperpile can reformat your document and generate the bibliography with one click. Simply chooseto 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:
Search for the journal or publisher whose style you would like to use, and a preview will show in the bottom of the window. Clickto update the citation style and reformat the document to see the changes.
You can edit a Paperpile-enhanced Google document with any number of collaborators, whether or not they already use Paperpile. Just click thebutton 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.
Paperpile supports the popular "citation style language" CSL with more then 8,000 citation styles available from citationstyles.org. 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 toand 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 editor.citationstyles.org. 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. You can then select this style in your Google document as described before.
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.
Here is some more information about how synchronization of your files to Google Drive works. Check out also the FAQs about syncing.
To check if a file is synced, open the file panel by clicking the paperclip symbol . The drive icon indicates the sync status of a file:
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.
To quickly share papers, select some items from your library and clickin the toolbar. The following dialog will appear:
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.
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 button next to the area in the left pane. Alternatively, you can select a few items your library and choose:
Paperpile will create a new folder and pre-populate it with your selected items (if applicable).
Click "Manage sharing" to invite new collaborators. The following dialog will appear:
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.
Clickto 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.
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.
Anyone with access to a shared folder can do the following:
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:
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.
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:
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.
You can download
PDFs with restricted access while off-campus through a proxy
connection provided by your institution or library.
Go to Settings > Proxy Access. Search for your institution or library and click.
Clickto 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
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. http://ezproxy.example.edu/login?url=$@. Note, the "$@" 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. Log in and verify that the connection is working (see above).
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:
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.
