The standard numbered citation format for electrical engineering, computer science, and technical fields.
Common questions about IEEE citation formatting
IEEE (Institute of Electrical and Electronics Engineers) citation style uses a numbered reference system. Each source is assigned a number in square brackets [1], [2], [3] in the order it first appears in the text. The reference list at the end is ordered numerically (not alphabetically). IEEE is the standard citation format in electrical engineering, computer science, information technology, and related technical fields.
IEEE in-text citations use numbers in square brackets. References are numbered in the order they first appear: [1], [2], [3]. When citing multiple sources, list the numbers separated by commas or use a dash for ranges: [1], [3], [5] or [1]-[3]. The number always refers to the same source throughout the paper. Place the citation number before any punctuation: as shown in [4].
In IEEE style, author names use initials before the surname, which is the opposite of most other citation styles. For example: J. K. Smith, not Smith, J. K. For two authors, use 'and' between them: J. Smith and R. Jones. For three or more authors, list all names separated by commas with 'and' before the last: J. Smith, R. Jones, and L. Lee. Up to six authors should be listed; for seven or more, list the first three followed by 'et al.'
An IEEE journal article reference follows this format: [1] A. B. Author, "Title of article," Abbreviated Journal Title, vol. X, no. Y, pp. start-end, Month Year, doi: 10.xxxx/xxxxx. Note that article titles use sentence case and are in quotation marks. Journal titles are abbreviated and italicized. The volume, issue number, page range, and date are all included when available.
IEEE conference paper format: [1] A. B. Author, "Title of paper," in Proc. Conference Name, City, State/Country, Year, pp. start-end. Conference papers are extremely common in IEEE fields. The paper title is in quotation marks with sentence case. The conference name is typically preceded by 'Proc.' (Proceedings of) and may be abbreviated. Include the city, state or country, year, and page range.
Yes, IEEE requires abbreviated journal titles in references. IEEE publishes an official list of journal title abbreviations. For example, 'IEEE Transactions on Pattern Analysis and Machine Intelligence' becomes 'IEEE Trans. Pattern Anal. Mach. Intell.' Common abbreviations include: Trans. (Transactions), J. (Journal), Lett. (Letters), Mag. (Magazine), Proc. (Proceedings). Always check the IEEE abbreviation list for the correct form.
