How do I cite the same source repeatedly in IEEE citation format?
If you cite the same source more than once in your writing, use the same number for all of the IEEE in-text citations for that source, and only include it on the IEEE reference page once. The source is numbered based on the first time you cite it.
For example, the fourth source you cite in your paper is numbered . If you cite it again later, you still cite it as . You can cite different parts of the source each time by adding page numbers [4, p. 15]. Don’t use “ibid.”
