CSE Name-Year Documentation
In this CSE citation system, references in your text give the last name of the author or authors and the year of publication within parentheses. These parenthetical refer to sources listed at the end of the document.
Contents of this page
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 ).
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 ) or soil (Merida and Loria ).
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. ), 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. ).
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. ; Kohn et al. ), 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 ), cows within a herd (e.g., breed, parity, stage of lactation; Godden et al. ), DHI test-day level of milk production (Johnson and Young ), method of sampling (morning vs. evening; Godden et al. ), method of analysis (Peterson et al. ; Kohn et al. ), and time-dependent factors such as month (Arunvipas et al. ) or season (Godden et al. ).
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 () and Gasith and Hasler () who examined spatial linkages between islands and the surrounding sea and terrestrial organic inputs into lakes, respectively.
Cite a source written by an organization
When citing an organization, corporation, or university as an author, use an abbreviation or acronym to avoid interrupting your text with a long citation.
Holstein dairy cows in the Dairy Herd Improvement program born in compared to had a percent-greater milk yield (26, pounds vs. 20, pounds) (AIPL ).
Here is what the reference list entry for this source would look like:
AIPL (Animal Improvement Program Laboratory), USDA. Trend in milk BV for Holstein [Internet]. [Cited 20 June ] Available from dfknj.wz.cz?R_Menu=HO#StartBody.
Cite a work cited by your source (secondary citation)
Secondary citations refer to material that you have not seen in its original form but rather have obtained from another document that cited the original source. In the edition of the CSE Manual, secondary citations are not listed as a valid form of citation. Instead, find and cite the original source.
Quote or excerpt a source
Although CSE provides rules for how to quote or excerpt sources, in practice almost no scientists publishing in journals that use CSE documentation choose to quote sources. Instead, these authors paraphrase or simply cite authors.
When you quote or excerpt a source, include an in-text reference to help your reader see what source you are quoting from. The seventh edition of the CSE Manual does not provide specific rules for identifying the page number or other location information for that source.
The below examples demonstrate how journals adapt CSE's guidelines to include page numbers after the year of publication:
Farmers participating in these knowledge networks, Hassanein writes, "challenged the power relations in agricultural knowledge production and distribution by relying on their own and members' experiential knowledge" (Hassanein , ).
Similarly, Hayward, Simpson, and Wood () describe "a mythologizing of the power of participatory methodologies to accomplish problem solving, emancipation or empowerment."
Cite multiple sources in a sentence
Multiple works by different authors
Put the sources in chronological order from oldest to most recent (and alphabetically if published in the same year). Separate studies by semicolon:
Readers curious about plant pathogenic bacteria are encouraged to explore the following and other older sources, which describe key research questions that remain unsolved (Smith ; Walker ; Schuster and Coyne ; Vidaver ; Mount and Lacy ; Starr ; Billing ; Nester ).
Theoretical studies suggest that plant diversity is a primary determinant of animal diversity (Hutchison ; Rosenzweig ; Knops et al. ), and experimental work has demonstrated a positive relationship between plant diversity and upper trophic-level diversity (Siemann ; Siemann et al. ; Knops et al. ; Koricheva et al. ; Haddad ).
Multiple works by the same author or set of authors (different years)
Cite them by naming the author, or set of authors, once and listing the years separated by commas:
Similarly, a series of epidemiological studies of P. syringae as a bean epiphyte and pathogen by Hirano and Upper laid the foundation for elegant experiments showing that type III secreted effectors and the Gac regulon are each critical for epiphytic fitness in the field; these important phenotypes were invisible in the controlled environment of a growth chamber (Upper and Hirano ; Hirano et al. , ).
Multiple works by the same author or set of authors (same year)
Add a letter after the year to help your reader see which source in your reference list you mean. Assign letters chronologically, so that the work that was published first is listed, for example, as a.
Mobile organisms that regularly traverse ecosystem boundaries have the capacity to deliver nutrients and energy, and affect consumers within a recipient ecosystem (Lundberg and Moberg ) including vertebrate (Sabo and Power b) and invertebrate taxa (Henschel et al. b, Yang ).
Here is what the end references for the Sabo and Power sources look like:
Sabo JL, Power ME. a. River-watershed exchange: effects of riverine subsidies on riparian lizards and their terrestrial prey. Ecology 83(7):
Sabo JL, Power ME. b. Numerical response of lizards to aquatic insects and short-term consequences for terrestrial prey. Ecology 83(11):
Multiple works by the same first author but by different additional authors (same year)
If you are citing works published by the same first author in the same year but with different groups of additional authors, CSE's official rule is that you should name as many authors as necessary for your reader to be able to distinguish each source.
Recent studies investigating the location of the Vitamin D3 receptor (Wang and DeLuca ; Wang, Borchert, et al. ; Wang, Marling, et al. ; Wang, Zhu, et al. ) suggest that . . .
However, many publishers simplify this rule so that the primary author in a group of 3 or more total authors authors is classed as one group. In other words, "Wang et al." counts as one author, even though the "et al." may be different people on different studies:
Recent studies investigating the location of the Vitamin D3 receptor (Wang and DeLuca ; Wang et al. a, b, c) suggest that . . .
End references and the reference list
The goal of your reference list is to help your reader identify each numbered source quickly and clearly. CSE has standardized the information to be provided for ease and predictability of reading.
What to call your reference list
"Reference list" is CSE's generic term for the list of sources at the end of your document. Your list should be given a more formal title: References or Cited References. If you used some documents as sources but did not cite them in your paper, list them alphabetically by author under the heading Additional References.
Format your end references
- Authors' first names are rendered as capitals after their surnames.
Otegui MS, Kiessling LL, Batzli J.
- The reference list is organized alphabetically by author's last name. When there is more than one work by an author, those works are organized chronologically.
Allen C, Bent A, Charkowski AO.
Bennett AB, Gratton C.
Bennett AB, Gratton C.
Gratton C, Vander Zanden MJ.
- Only the first word of a book or article title should be capitalized.
The fat-soluble vitamins: handbook of lipid research 2.
- Titles are not italicized. However, species names are italicized.
In vitro and in vivo reconstitution of the cadherin-catenin-actin complex from Caenorhabditis elegans.
- To save space, journal titles are abbreviated according to the ISO 4 standard, shortening significant words and omitting insignificant words. Read more and search the List of Title Word Abbreviations at dfknj.wz.cz
Livestock Prod Sci.
Biochem Mol Biol Educ.
J Dairy Sci.
- Year of publication and volume number are required for all references to articles. Issue number is strongly recommended. To save space, use no spaces to separate an article's date, volume, and page.
