Ratios for Evaluating Full-Text Journal Article Access: A Quantitative Study

Abstract

ABSTRACT This article proposes a methodology for systematically assessing the cost of journal subscriptions. The authors of the paper (hereafter “the researchers”) established ratios comparing the list costs of journal articles as advertised by publishers against the cost per article of journal articles available in aggregated collections in library databases (hereafter “aggregating databases”). The researchers propose that the ratios can be used by libraries wishing to apply a standard methodology for assessing journal packages containing full-text articles. The study may be helpful for those librarians who seek to supplement qualitative information and other quantitative data, such as usage statistics, in order to demonstrate the library's rationale for providing journal access either by purchasing articles directly from a publisher as needed or by continuing to subscribe to an aggregating database. The aggregating databases reviewed in this study included representative aggregating databases commonly associated with the following fields of study: Social Sciences, Humanities, and Health Sciences; however, the methodology described in this article could be applied to other disciplines as well. The results of the study indicated that the ratios for Mean Cost/Package Subscription Price (MC/PSP), Median Cost/Package Subscription Price (MED/PSP) could be used in evaluating journal collections. The researchers suggest that future studies should be conducted to assess resource sharing and the availability of open access resource versions of articles as possible contributing factors to the purchase decisions associated with scholarly journal articles.
