Proving the Value of Library Collections Part II: An Interdisciplinary Study Using Citation Analysis
- 1. PROVING THE VALUE OF LIBRARY COLLECTIONS PART II: An Interdisciplinary Study Using Citation Analysis Lea Currie, Head of Content Development, University of Kansas Libraries lcurrie@ku.edu Amalia Monroe-Gulick, Strategy & Assessment Librarian, University of Kansas Libraries almonroe@ku.edu
- 2. Project Objectives: 1. Prove the value of the KU Libraries by demonstrating that the Libraries provide access to the necessary resources that faculty use to conduct their research. 2. Identify weaknesses in the library collections that could be corrected
- 3. Research Questions: 1. What formats are used by faculty? 2. Items available electronically, in print, or both? 3. What is the age of the cited items? 4. How are the cited journals purchased? 5. What are the most frequently cited publishers? 6. Do citation patterns vary among the disciplines?
- 4. Methodology: 1. Journal articles published 2005 to the present were used as parameters for inclusion in the analysis 2.Each citation was analyzed to record the following data: • Publisher • Publication date • Format (journal article, book, report, etc.) • Call number • KU availability • Print access • Electronic access • Journal package access • Aggregator database access

- Consulted departmental web sites and randomly selected faculty. Student assistants downloaded the faculty CV’s and copied and pasted the list of citations in each of their publications into a spreadsheet. The sample size was different for each broad area because of the large variance in the number of citations in the broad subject areas. The citations were randomized in Excel and 22% of the citations collected were actually analyzed. (3222 out of 14,541). WE concentrated our analysis on journals and books. Each citation was searched in WorldCat and this data was collected. Limitations were noted – We had no way of knowing if the materials in the sample were accessible during the time the research was actually conducted, so we agreed that currently available publications would be recorded as accessible. We were also concerned that the CV’s may not be current, which could also skew the results of our study.

- We were gratified to find out we provided satisfactory coverage in all subject areas.We were a little mortified to find some much overlap in formats, since we have made a concerted effort to de-duplicate print and electronic journals. This is probably due to publishers’ policies not to allow cancellation of print without losing access to electronic journals. Happy to see that expensive packages and aggregators are being used.Surprised at the older publication dates, especially in the sciences.Surprised to see that faculty in the social sciences still use quite a few books.Happy that given the amount of money we spend on the top publishers, they are widely used by all of the disciplines.
