How to format your references using the BMC Medical Research Methodology citation style

This is a short guide how to format citations and the bibliography in a manuscript for BMC Medical Research Methodology. 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	Download the output style file
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.

1. Hirschmann MM. Geochemistry. Ironing out the oxidation of Earth’s mantle. Science. 2009;325:545–6.

A journal article with 2 authors

1. Volkman SK, Hartl DL. Parasitology. A game of cat and mouth. Science. 2003;299:353–4.

A journal article with 3 authors

1. Angell SY, Danel I, DeCock KM. Global health. Global indicators and targets for noncommunicable diseases. Science. 2012;337:1456–7.

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

1. Government Accountability Office. Science And Technology: Air Force’s Planning Process Meets Statutory Requirement. Washington, DC: U.S. Government Printing Office; 2002.
