STEM Research Guide

What is CSE style?

• A documentation style for writing and formatting scientific research papers, including citing sources
• Created by the Council of Science Editors
• Scientific Style and Format contains comprehensive and explanations for proper scientific communication and style guidelines
• CSE offers three style options for in-text citations: Citation-Sequence System, Name-Year System, and Citation-Name System

How to cite in CSE

1. Citation-Sequence System

In Text:

• Use a superscript number at the end of a sentence to acknowledge that you are using another author's words or ideas in the text of your research paper.
• Number citations in the order they appear in the text.
• If you cite the same source again later in your paper, use the number you assigned originally; each source should be associated with one and only one number.

Reference List:

• Include a reference list at the end of your paper. The list should contain a full citation for each in-text citation referenced within your paper.
• Each full citation should include the specific publication information required by the Council of Science Editor rules. This allows your reader to find the sources, if desired.
• Arrange the end references in numerical order according to the order they appear in the paper.

 

2. Citation-Name System

Reference List:

• Include a reference list at the end of your paper. The list should contain a full citation for each in-text citation referenced within your paper.
• Each full citation should include the specific publication information required by the Council of Science Editor rules. This allows your reader to find the sources, if desired.
• Arrange citations in alphabetical order by the first word of the citation (usually author's last name). Then, number the sources sequentially.

In Text:

• Use a superscript number at the end of a sentence to acknowledge that you are using another author's words or ideas in the text of your research paper.
• Use the number assigned to the source in the reference list.

 

3. Name-Year System

In Text:

• Provide in-text citations in parentheses at the end of a sentence to acknowledge that you are using another author's words or ideas in the text of your research paper. In-text citations should consist of the last name of the author (or authors) and the year of publication.
  • Example: (Smith 2019)
• For sources with two authors, list surnames separated by “and".
  • Example: (Smith and Jones 2019)
• For sources with three or more authors, give only the first author’s name followed by et al.
  • Example: (Smith et al. 2019)
• When citing two sources with the same author but different publication years, separate the years with a comma.
  • Example: (Smith 2013, 2019)
• To distinguish between two sources published by the same author in the same year, add a lower-case letter to the year in both the in-text and reference list entries. Assign letters alphabetically in chronological order of publication.
  • Example: (Smith 2019a, 2019b)
• When citing two different sources that have authors with the same surname and publication year, include the authors' first initials in the in-text reference and, if cited together, separate the references by a semicolon.
  • Example: (Smith J 2019; Smith M 2019)

Reference List:

• Include a reference list at the end of your paper. The list should contain a full citation for each in-text citation referenced within your paper.
• Each full citation should include the specific publication information required by the Council of Science Editor rules. This allows your reader to find the sources, if desired.
• Do not number the reference list. Arrange the end references alphabetically by the author’s last name.
• In the reference list, multiple sources by the same author should be listed chronologically, earliest first.
