The ultimate guide to citing in CSE
CSE style was developed by the Council of Science Editors (CSE), a US-based nonprofit organization that supports editorial practice among scientific writers. The CSE publishes a style guide for scientific papers: The CSE Manual. CSE style originated in the 1960s and is currently used in many fields of study in both the life sciences and physical sciences.
If you are not sure which citation style to use in your paper, ask your instructor. There are many different citation styles and using the style your instructor or institution has established correctly can have a positive impact on your grade.
The CSE Manual, 8th edition, is the basis of this guide. This guide focuses on crediting sources and aims at answering all of your questions about citing in CSE. But you don’t have to worry about getting your citations right with the BibGuru citation generator. We have created BibGuru to help you focus on the content of your work instead of worrying about how to get your reference list done correctly.

In-text citations in CSE
The CSE style has three systems to cite sources in-text:
- Name-Year (N-Y) system: The author’s surname and year of the publication are placed in parentheses in the text e.g. (Rode 2012). The reference list is ordered alphabetically by author name.
- Citation-Name (C-N) system: Superscript numbers are used to identify in-text citations. In the alphabetized reference list, each numeral corresponds with a unique reference.
- Citation-Sequence (C-S) system: Superscript numbers are used to identify in-text citations. In the reference list, sources are numbered sequentially by the order in which they appear in the text (this differs from the C-N system because they might not be in alphabetical order by author).
These abbreviated references are called in-text references. They refer to a list of full references at the end of the document.
Which of the three citation systems above you use will determine the order of references at the end of your document. These end references essentially have the same format in all three systems. One exception is the placement of the date of publication in the name-year system. Ask your instructor which of the three systems to use in case you are unsure.
CSE reference list - Name-Year system
See below the format and examples for the most popular reference types in the name-year system:

For the end reference, list authors in the order in which they appear in the original text, followed by the year of publication. Journal titles are generally abbreviated. Each element is separated by a period, and the location (usually the page range for the article) is preceded by a colon.

For articles with 3 to 10 authors, list all authors in the end reference; in the in-text reference, list only the first, followed by “et al.” When there are more than 10 authors, list the first 10 in the end reference, followed by “et al.”

The basic format for books is as follows:
FORMATBook
Author(s). Date. Title. Edition. Place of publication: publisher. Extent. Notes.
Extent can include information about pagination or number of volumes and is considered optional. Notes can include information of interest to the reader, such as the language of publications other than English, and is also considered optional.
For books with 2 authors, names are separated by a comma in the end reference and by “and” in the in-text reference.

For the in-text reference, include only the first word or two of the title (enough to distinguish it from other titles in the reference list), followed by an ellipsis.

CSE reference list - Citation-Sequence and Citation-Name system
The citation-sequence and citation-name systems are identical except for the order of references. In both systems, numbers in the text refer to references in the reference list.
In the citation-sequence system, the end references are listed in the order in which they appear in the text. Once a reference is numbered, the same number is used for all following in-text citations in the same document, e.g. if Meyer is the first mentioned in-text, their work will be number 1 in the end references and also in all following in-text references.
In the citation-name system, references in the reference list are listed alphabetically by author. Multiple works by one author are listed alphabetically by title. The end references are numbered in alphabetical order and the number assigned to an author in the reference list is then used for the in-text citations, regardless of the order in which they appear in the text. So, if a work by Meyer is number 43 in the reference list, each in-text reference to Meyer will also be number 43.

FAQs
🐙 What does CSE stand for?
CSE stands for Council of Science Editors, formerly known as Council of Biology Editors, CBE. It is a US-based non-profit organization supporting editorial practice among scientific writers. The CSE was established in 1957 by the National Science Foundation and the American Institute of Biological Sciences. The CSE publishes a style guide for scientific papers, the CSE Manual.
🏈 What is the CSE style used for?
The Council of Science Editors (CSE), a US-based non-profit organization supporting editorial practice among scientific writers publishes a style guide for scientific papers: The CSE Manual. The style is used in many fields of study including the life sciences and physical sciences.
📻 Does the CSE style use footnotes?
The CSE style has three systems to cite sources. The Name-Year system uses in-text citations. In the Citation-Name system and the Citation-Sequence system, superscript numbers are used in-text to identify citations, corresponding with references in the reference list. Those are similar to footnotes but different in that they are not listed separately but integrated into the text.
🎤 How do I cite an interview in CSE?
Interviews and other forms of unpublished personal communications (for example emails) are not included in the reference list in the CSE style. Instead, they should be cited in parentheses within the text of your paper.
📀 What are the citations called that are listed at the end of a CSE paper?
The reference list (or bibliography) at the end of your CSE paper can be titled "References" or "Cited References". The arrangement of those references depends on which of the three style systems you picked for the citations of your paper.
