How to format your references using the Machines citation style

This is a short guide how to format citations and the bibliography in a manuscript for Machines. 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:

PaperpileThe citation style is built in and you can choose it in Settings > Citation Style or Paperpile > Citation Style in Google Docs.
EndNoteFind the style here: output styles overview
Mendeley, Zotero, Papers, and othersThe style is either built in or you can download a CSL file that is supported by most references management programs.
BibTeXBibTeX 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
Roff, D. Evolution. Evolutionary Danger for Rainforest Species. Science 2003, 301, 58–59.
A journal article with 2 authors
Green, D.J.; Alemseged, Z. Australopithecus Afarensis Scapular Ontogeny, Function, and the Role of Climbing in Human Evolution. Science 2012, 338, 514–517.
A journal article with 3 authors
Shay, J.W.; Reddel, R.R.; Wright, W.E. Cancer. Cancer and Telomeres--an ALTernative to Telomerase. Science 2012, 336, 1388–1390.
A journal article with 4 or more authors
Stellamanns, E.; Uppaluri, S.; Hochstetter, A.; Heddergott, N.; Engstler, M.; Pfohl, T. Optical Trapping Reveals Propulsion Forces, Power Generation and Motility Efficiency of the Unicellular Parasites Trypanosoma Brucei Brucei. Sci. Rep. 2014, 4, 6515.

Blog post

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 Technology Assessment: Explosives Detection Technologies to Protect Passenger Rail; U.S. Government Printing Office: Washington, DC, 2010;

Theses and dissertations

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

Doctoral dissertation
Lam, N.N. The Effect of Racial Disparities and Adult Supervision in Human Papillomavirus Knowledge among Female Adolescents. Doctoral dissertation, California State University, Long Beach: Long Beach, CA, 2013.

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

In-text citations

References should be cited in the text by sequential numbers in square brackets:

This sentence cites one reference [1].
This sentence cites two references [1,2].
This sentence cites four references [1–4].
