CSE Citation Style

Name-Year Citations

CSE's name-year in-text reference takes the form of the author's last name and the year of publication, in parentheses.

Cite a source written by one author
The rapid discovery of the unique mechanisms underlying crown gall disease demonstrated how quickly an area could advince given significant investment and competition (Zambryski 1988).

Cite a source written by two authors
Initial infection of tubers by H. solani occurs in the field either from the seed tuber (Jellis and Taylor 1977) or soil (Merida and Loria 1994).

Cite a source written by three or more authors
For example, terrestrial carbon can play a central role in supporting lake food webs (Pace et al. 2004), while the problem of aquatic ecosystem
eutrophication is driven by urban and agricultural land use that contributes nutrients to downstream aquatic systems (Carpenter et al. 1998).

Where to cite

Cite sources as close as practicable to the information they support. This might mean citing a source at the end of a sentence or in the middle of a sentence. This might lead to long sentences, with citations immediately following the topics with which those sources are associated:

Although "target" ranges of MUN have been proposed (Hof et al. 1997; Kohn et al. 2002), its use as a management tool on farms remains uncertain because of permanent or temporary effects specific to herds (e.g., rolling herd average for milk production; Rajala-Schultz and Saville 2003), cows within a herd (e.g., breed, parity, stage of lactation; Godden et al. 2001), DHI test-day level of milk production (Johnson and Young 2003), method of sampling (morning vs. evening; Godden et al. 2001), method of analysis (Peterson et al. 2004; Kohn et al. 2004), and time-dependent factors such as month (Arunvipas et al. 2003) or season (Godden et al. 2001).

If you name your author in the sentence near the citation, you do not need to repeat that name in the citation itself:

In this study we develop a conceptual model for understanding the linkages between aquatic habitats and the surrounding terrestrial landscape, building on ideas presented by Polis and Hurd (1996) and Gasith and Hasler (1976) who examined spatial linkages between islands and the surrounding sea and terrestrial organic inputs into lakes, respectively.

No author
► If the author cannot be determined, do not use "anonymous."  Instead, substitute it with an organization name if one is available. If there is no organization, use the first word or few words of the title, followed by ellipsis. Only use enough words of the title to distinguish it from other titles.

► Occasionally it is not possible to determine any date associated with a publication.  If the document was found online, use the date you viewed it instead.  Alternatively for print publications, place the words "date unknown" within square brackets.
