Properly formatted references are a critical part of any academic or engineering paper. They demonstrate credibility, help readers locate your sources, and ensure compliance with journal requirements. Among the many referencing styles, IEEE (Institute of Electrical and Electronics Engineers) style is the standard for engineering, computer science, and technical research.
In this guide, we provide a practical step-by-step approach to formatting references in IEEE style, complete with examples. We also explain common pitfalls, best practices, and tools you can use to simplify the process.
IEEE style is a numeric citation style used in engineering and technical fields. Key characteristics include:
References are numbered in the order they appear in the text.
Citation numbers are placed in square brackets, e.g., [1], [2], [3].
The reference list at the end of the document is ordered numerically, not alphabetically.
Specific formatting rules apply to books, journals, conference papers, websites, and other sources.
Consistency: Ensures all sources are cited in a uniform way.
Clarity: Readers can easily match in-text citations to the reference list.
Journal Compliance: Many engineering journals require IEEE formatting for submission.
Professional Presentation: Properly formatted references reflect attention to detail and academic rigor.
In IEEE style, citations are numbered in the order they first appear in your text. For example:
Correct: Recent studies [1], [2] have shown that…
Later references continue the sequence: …as demonstrated in [3] and [4].
Tips:
Use square brackets for all in-text citations.
Maintain a single numbering sequence throughout the paper.
Do not reuse numbers for different sources.
The standard IEEE format for a journal article is:
Format:[Ref Number] Author Initials. Last Name, "Title of the article," Journal Name, vol. Volume, no. Issue, pp. Pages, Month Year.
Example:[1] J. A. Smith and K. B. Lee, "Advanced control techniques for autonomous robots," IEEE Trans. Robot., vol. 35, no. 4, pp. 1023-1032, Aug. 2020.
Notes:
Abbreviate journal names according to IEEE guidelines.
Include volume, issue, page numbers, and month/year of publication.
The standard IEEE format for a book is:
Format:[Ref Number] Author Initials. Last Name, Title of the Book, xth ed. City of Publisher, Country: Publisher, Year.
Example:[2] P. Brown, Modern Control Systems, 14th ed. Boston, MA, USA: Pearson, 2021.
Tips:
Include edition if not the first.
Always mention the city and publisher.
Conference papers have a slightly different format:
Format:[Ref Number] Author Initials. Last Name, "Title of paper," in Proc. Conference Name, City, Country, Year, pp. Pages.
Example:[3] T. Nguyen, "Real-time signal processing for IoT devices," in Proc. IEEE Int. Conf. Acoust., Speech, Signal Process., Barcelona, Spain, 2021, pp. 345-349.
Notes:
Use “Proc.” for Proceedings.
Include city, country, year, and page numbers.
IEEE has a standard format for online resources:
Format:[Ref Number] Author (if available), "Title of web page/document," Website Name. [Online]. Available: URL. [Accessed: Month Day, Year].
Example:[4] World Health Organization, "Global energy-efficient technologies," WHO. [Online]. Available: https://www.who.int/energy-tech. [Accessed: Dec. 15, 2023].
Tips:
Include access date because web content can change.
If no author, start with the organization name.
Theses/Dissertations:[Ref Number] Author Initials. Last Name, "Title of thesis," M.S. thesis or Ph.D. dissertation, University, City, Country, Year.
Example:[5] M. Al-Sayed, "Advanced robotics navigation algorithms," Ph.D. dissertation, King Saud Univ., Riyadh, Saudi Arabia, 2020.
Reports:[Ref Number] Author or Organization, "Title of report," Report Number, City, Country, Month Year.
Patents:[Ref Number] Inventor Initials. Last Name, "Title of patent," Country Patent xxxxx, Month Day, Year.
Formatting IEEE references manually can be tedious. Tools like EndNote, Zotero, Mendeley, or Microsoft Word citation manager allow you to:
Automatically format references in IEEE style
Maintain consistency between in-text citations and the reference list
Quickly update references when adding or removing sources
Numbering citations out of order
Omitting volume, issue, or page numbers
Incorrect abbreviation of journal names
Missing access date for websites
Mixing different citation styles in the same paper
Double-check all details: Author initials, spelling, publication year, and page numbers.
Be consistent: Every reference and in-text citation must match exactly.
Follow the journal’s specific rules: Some journals have slight variations of IEEE style.
Keep a master reference list: Update it as you write to avoid missing citations.
Use professional tools: Reference managers reduce human error and save time.
