IEEE citation style


This guide provides some basic models and examples of citations based primarily on the IEEE Reference Guide, which is part of the IEEE Editorial Style Manual.

IEEE requires any citation and style issues not covered by its own style manual to be addressed using the Chicago Manual of Style. Submitting an article to an IEEE publication may require using that publication's style, which occasionally varies from the general IEEE style. Learn more from the IEEE Author Center.

General Guidelines

In-text citation

  • In-text citations are shown as numbers within square brackets, for example “According to [2]…”, “As demonstrated in [3]–[5]…”.
  • The numbers increase sequentially with each additional source that you cite.
  • If you cite the same source more than once, use the same number rather than creating a new reference. Remember that if you move text with a citation after writing your document, you must resequence your references to correspond.
  • Do not say “in reference [1] …”; rather, the text should be written to read simply, “in [3] …”.
  • The author’s name generally should not be included in a text reference with a number (i.e., “In Patel [1]”) and should be changed to “in [3]” except in such cases where the author’s name is integral to the understanding of the sentence (e.g., “Patel [3] reduced calculated time …”).

Reference list

  • Reference numbers are aligned to the left margin and form a column of their own.
  • Use "et al." to signify that a document has more than six authors.
  • All references, except those ending with URLs, will end with a period, including those with a DOI.
  • Check the IEEE Editorial Style Manual for official abbreviations. Many commonly used terms as well as specific IEEE journals should be abbreviated in the references.

Dataset, table, and graph


Due to the various techniques for accessing and storing datasets (research data management guide), the citation rules are not as commonly defined as they are for things like books or journal articles. The IEEE Editorial Style Manual does not explicitly state how to cite data.

The following was adapted from The Chicago Manual of Style's guidance in "14.257: Citing data from a scientific database." The manual recommends that the citation include the database's name and some description of the record being cited (a data marker or accession number). It should also include the date that you accessed it and a URL.

Model for data from a scientific database

  1. DB Name (descriptive phrase [record locator]; accessed date). site/path/file



  1. Laser-Induced Breakdown Spectroscopy (LIBS) dataset for materials for Planetary Exploration (LIBS Dataset [AnorthoMO11 1000AVG]; accessed February 28, 2018).

See the DataCite Canada recommendations for additional detail about good practices for citing data. You can also find documentation detailing different data citation use-cases in the guide from The Digital Curation Centre.


The 17th edition of The Chicago Manual of Style offers some guidance on data in the context of using it in tables (section 3.77 Acknowledging data in source notes to tables). Chicago requires the full source to be cited.

For example, if you use data from a source such as a book or an article to create a table in your document, Chicago requires that you identify that data by writing "Data from [Name of the source]" within a footnote. You must also include that source in your reference list the way you normally would (e.g. if it's an article, format it like an article reference).

IEEE formatting style for footnotes is in section "B. Editing the Body of a Paper" of the IEEE Editorial Style Manual.


If you use an image such as a graph from another source, make sure to label it with a caption using the rules under "Text Citation of Figures and Tables" in part "II. Editing Principles," section "B. Editing the Body of a Paper" of the IEEE Editorial Style Manual. The graph may require a reference number or additional source information depending on whether or not it's from an IEEE source.

The IEEE Editorial Style Manual does not explicitely describe how to cite lectures. The following was adapted from the Chicago Manual of Style's guidance in "14.217: Lectures and papers or posters presented at meetings." If lecture notes or recordings are accessible online you can add an electronic resource to the reference.

Model for a lecture or presentation

  1. J. K. Lecturer, “Title,” Lecture, Title of course, Organization, location, Date.

Model for lecture notes that can be accessed online

IEEE also recommends using the following format for documents such as datasheets or corporate handbooks.

Generative AI (eg., ChatGPT)

There is currently no official stylistic recommendations from IEEE for referencing AI-generated content. IEEE requires any citation and style issues not covered by its own style manual to be addressed using the Chicago Manual of Style. If you have been asked to cite material generated by artificial intelligence for a class assignment, you can use the format suggested by the Chicago Manual of Style.


  1. Text generated by ChatGPT, June 28, 2023, OpenAI,

Note: Methods of citing materials generated by artificial intelligence (AI) tools like ChatGPT are rapidly changing. Check with your course instructor or thesis supervisor before using or citing material generated by AI tools. You should also check whether the tool you’re using has terms of use or guidelines on how to credit use of the tool (for example, from OpenAI).
