How to format your references using the ZooKeys citation style

This is a short guide how to format citations and the bibliography in a manuscript for ZooKeys. For a complete guide how to prepare your manuscript refer to the journal's instructions to authors.

Using reference management software

Typically you don't format your citations and bibliography by hand. The easiest way is to use a reference manager:

Paperpile	The citation style is built in and you can choose it in Settings > Citation Style or Paperpile > Citation Style in Google Docs.
EndNote	Find the style here: output styles overview
Mendeley, Zotero, Papers, and others	The style is either built in or you can download a CSL file that is supported by most references management programs.
BibTeX	BibTeX syles are usually part of a LaTeX template. Check the instructions to authors if the publisher offers a LaTeX template for this journal.

Journal articles

Those examples are references to articles in scholarly journals and how they are supposed to appear in your bibliography.

Not all journals organize their published articles in volumes and issues, so these fields are optional. Some electronic journals do not provide a page range, but instead list an article identifier. In a case like this it's safe to use the article identifier instead of the page range.

A journal article with 1 author

Ensign SA (2011) Microbiology. Another microbial pathway for acetate assimilation. Science (New York, N.Y.) 331: 294–295.

A journal article with 2 authors

Suarez RK, Jones DR (2002) Obituary: Peter W. Hochachka (1937-2002). Nature 420: 140.

A journal article with 3 authors

Shikano Y, Wada T, Horikawa J (2014) Discrete-time quantum walk with feed-forward quantum coin. Scientific reports 4: 4427.

A journal article with 4 or more authors

Web sites

Sometimes references to web sites should appear directly in the text rather than in the bibliography. Refer to the Instructions to authors for ZooKeys.

Blog post

Andrew E (2015) Doomsday Clock Moves Closer To Midnight, But Can We Really Predict The End Of The World? IFLScience. Available from: https://www.iflscience.com/environment/doomsday-clock-moves-closer-midnight-can-we-really-predict-end-world/ (October 30, 2018).

Reports

This example shows the general structure used for government reports, technical reports, and scientific reports. If you can't locate the report number then it might be better to cite the report as a book. For reports it is usually not individual people that are credited as authors, but a governmental department or agency like "U. S. Food and Drug Administration" or "National Cancer Institute".

Government report

Government Accountability Office (2007) Passenger Rail Security: Federal Strategy and Enhanced Coordination Needed to Prioritize and Guide Security Efforts. U.S. Government Printing Office, Washington, DC

Theses and dissertations

Theses including Ph.D. dissertations, Master's theses or Bachelor theses follow the basic format outlined below.

Doctoral dissertation

Daczo Z (2012) Wage inequality and the gender wage gap: Are American women swimming upstream? Doctoral dissertation. University of Maryland, College Park

News paper articles

Unlike scholarly journals, news papers do not usually have a volume and issue number. Instead, the full date and page number is required for a correct reference.

New York Times article

Hodgman J (2016) Bonus Advice From Judge John Hodgman. New York Times: MM24.

In-text citations

References should be cited in the text by name and year in parentheses:

This sentence cites one reference (Ensign 2011).
This sentence cites two references (Suarez and Jones 2002, Ensign 2011).

Here are examples of in-text citations with multiple authors:

Two authors: (Suarez and Jones 2002)
Three or more authors: (Carette et al. 2011)
