Abstract

The main objective of collection management in libraries is to provide information sources needed by library users. The most frequently used information sources in collections are determined by carrying out usage analysis studies. This paper aims to investigate the most frequently used journal titles along with their subjects and years, and the relationship between journal use and impact factors. Transaction logs of more than one million articles that were downloaded from ScienceDirect electronic journals database by the users of Hacettepe University Libraries during 2002-2006 were used for analysis. Each record contained COUNTER-based (Counting Online Usage of Networked Information Resources) data about downloaded article (such as journal name, year, and so on). More articles were downloaded in health sciences. The average number of downloaded articles per journal were higher in chemistry, pharmacology, chemical engineering, medicine and neurology. Journals with high impact factors were also used more often (Pearson’s r = .194, p < .01). A small number of core journals in each subject satisfied one third of all downloaded articles. These findings will help Hacettepe University Libraries better manage its licensed journals collection. Training sessions can be increased for ScienceDirect journals (and subjects) that were less-frequently used. Use data can be used to support license agreements.
