The practice of citing references is integral to scholarship. This paper focuses on three prominent journals for library science: College and Research Libraries, Library Resources and Technical Services, and Reference and User Services Quarterly. Errors in both citations and quotations were found in all three journals, although no statistically significant differences among journals were discovered. Citation errors of less than 10 percent were found for all three journals, while in total, 30.3 percent of quotations were judged to be questionable in some way. The paper includes recommendations for authors, editors and librarians. It also recommends further study of errors in quotations, which appear more troubling than those in citations.
