Dear APA Style Experts,
When should I use ibid. in my research paper? I want to cite the same source multiple times in a row, but I’m not sure how. Please help!
Ibid. is one of several topics not covered in the Publication Manual because it isn’t used in APA Style. Other styles that document sources with footnotes or endnotes use ibid. to point to a source that was cited in a preceding note. APA Style, however, consistently uses the author–date format to identify an idea’s origin.
When repeatedly referring to the same source, it’s not always necessary to include a parenthetical citation at the end of every paraphrased sentence, as long as the narrative plainly indicates where the information is coming from. Even a direct quotation may not require a full parenthetical citation in this case—you can vary your citation style. If you’re not sure whether your paper clearly shows that you’re drawing multiple thoughts from one source, just ask your instructor, a classmate, or someone at your school’s writing center to give it a quick read. One of the most valuable resources in any form of writing is a second pair of eyes!
I hope this post answered your question, Brann! You can also turn to pages 174–175 of the Publication Manual for examples that show how to integrate citations into the narrative and when to include the publication date. Also be sure to check out one of our earlier posts that briefly reviews how to create in-text citations. And, as always, feel free to comment on this post, leave us a note on Twitter or Facebook, or contact us directly about any questions you may have.
