Do Science Researchers Use Books? Nisa Bakkalbasi Science/Electronic Resources Librarian Purchase College State University of New York nisa.bakkalbasi@purchase.edu David Goodman Associate Professor Palmer School of Library and Information Science Long Island University david.goodman@liu.edu XXIV Annual Charleston Conference: Issues in Books and Serials Acquisition Charleston, South Carolina November 2004
Introduction • In this study we examine citation data for books that have been cited in the journal articles that were published by authors at a large university during 1981-2001 • Most recent investigations have examined use of journal articles, not books. • Local citation data as a measure of book use. Charleston Conference November 2004
Data Source Results are based on citation data extracted from Web of Science. A sample record from raw data containing 1,441 records. Charleston Conference November 2004
Data Source The dataset have undergone a detailed processing and cleaning. We excluded all records with less than 8 citations. Charleston Conference November 2004
Descriptive Statistics A total number of 1,132 titles are analyzed. The total number of citations for all titles is 17,657. Charleston Conference November 2004

Citation Age by Selected Disciplines Biology and Physics appear to be representative of all disciplines. Charleston Conference November 2004
Citation Age by Selected Disciplines Mathematics and Astronomy appear to behave differently at early ages. Charleston Conference November 2004
Lifespan of a Book Book citations increase rapidly within the first 4 years of its lifespan Charleston Conference November 2004
Summary • The citation data conforms to Zipf’s Law. • Most citations are to recent titles with observable similarities and differences across different scientific disciplines. • On average, citations increase rapidly within the first 4 years of publication date. Charleston Conference November 2004
Conclusion • Researchers are citing books. • Scientists still rely on books while performing research as a source of information. Charleston Conference November 2004
