Abstract
This study is a citation analysis of a set of theses and dissertations in the Ohio State University's online catalog, for which the author-assigned keywords and cataloger-assigned Library of Congress Subject Headings (LCSH) are known. Correlations are sought between the types and ages of resources cited and the number of unique keywords and unique LCSH that were found. The author presents results found in three general discipline areas: arts and humanities, the social sciences, and science, technology, engineering, and medicine.
