Using reference management software

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

Schimpf, D. (2000). A benefit of being big. Science (New York, N.Y.), 290(5491), 453c.

A journal article with 2 authors

Czakó, G., & Bowman, J. M. (2011). Dynamics of the reaction of methane with chlorine atom on an accurate potential energy surface. Science (New York, N.Y.), 334(6054), 343–346.

A journal article with 3 authors

Tanner, C., Manca, C., & Leutwyler, S. (2003). Probing the threshold to H atom transfer along a hydrogen-bonded ammonia wire. Science (New York, N.Y.), 302(5651), 1736–1739.

A journal article with 8 or more authors

Blog post

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). Transportation Accessibility: Lack of Data and Limited Enforcement Options Limit Federal Oversight (No. GAO-07-1126). Washington, DC: U.S. Government Printing Office.

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

Doctoral dissertation

Hoover, J. H. (2009). The Arizona water-energy nexus: Electricity for water and wastewater services (Doctoral dissertation). University of Arizona, Tucson, AZ.

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

Grynbaum, M. M. (2017, June 23). The Incredible Shrinking White House Briefing. New York Times, p. A15.

In-text citations

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

This sentence cites one reference (Schimpf 2000).
This sentence cites two references (Czakó and Bowman 2011; Schimpf 2000).

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

Two authors: (Czakó and Bowman 2011)
