How to format your references using the GSA Today citation style

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

Williams, E., 2011, Environmental effects of information and communications technologies: Nature, v. 479, p. 354–358.

A journal article with 2 authors

Boehme, C., and McCamey, D.R., 2012, Physics. Nuclear-spin quantum memory poised to take the lead: Science (New York, N.Y.), v. 336, p. 1239–1240.

A journal article with 3 authors

Patt, A.G., Ogallo, L., and Hellmuth, M., 2007, Sustainability. Learning from 10 years of climate outlook forums in Africa: Science (New York, N.Y.), v. 318, p. 49–50.

A journal article with 11 or more authors

Pfleiderer, C., Reznik, D., Pintschovius, L., Löhneysen, H.V., Garst, M., and Rosch, A., 2004, Partial order in the non-Fermi-liquid phase of MnSi: Nature, v. 427, p. 227–231.

Books and book chapters

Here are examples of references for authored and edited books as well as book chapters.

An authored book

Bonem, J.M., 2011, Problem Solving for Process Operators and Specialists: Hoboken, NJ, John Wiley & Sons, Inc.

An edited book

Rodrìguez-Merchán, E.C. (Ed.), 2012, Articular Cartilage Defects of the Knee: Diagnosis and Treatment: Milano, Springer, VI, 117 p. 44 illus., 26 illus. in color p.

A chapter in an edited book

D’Alessandro, C., and Léautier, F., 2016, Leadership, Spirals, and Trajectories, in Léautier, F. ed., Cities and Spaces of Leadership: A Geographical Perspective, London, Palgrave Macmillan UK, p. 54–76.

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 GSA Today.

Blog post

Hamilton, K., 2015, Super Active Sun Knocks Out Global Radio With Huge Solar Flare: IFLScience, https://www.iflscience.com/space/slooh-hosts-live-broadcast-super-active-sun/ (accessed October 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, 2004, Aviation Security: Factors Could Limit the Effectiveness of the Transportation Security Administration’s Efforts to Secure Aerial Advertising Operations: U.S. Government Printing Office GAO-04-499R.

Theses and dissertations

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

Doctoral dissertation

Calhoun, G.F., 2009, Limit theory for overfit models [Doctoral dissertation]: University of California San Diego.

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

Mueller, B., Wang, V., and Piccoli, S., 2017, 3 Men From Shelter Held in Sexual Assault on Woman Leaving Church: New York Times, p. A17.

In-text citations

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

This sentence cites one reference (Williams, 2011).
This sentence cites two references (Williams, 2011; Boehme and McCamey, 2012).

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

Two authors: (Boehme and McCamey, 2012)
Three or more authors: (Pfleiderer et al., 2004)
