The purpose of this study is to contribute to the establishment of metrics that can be used by libraries to analyze, anticipate, and plan for resource allocation for specialized print-based collections within an academic library. In the context of transactions associated with the circulation of library materials, that is checkouts, renewals, and holds, the resources this study will propose includes two ratios that can be used for evaluating and justifying continued allocation of library resources to specialized print collections. These ratios proposed are the Proportionate Number (P/N) and Internal P/N (I-P/N) Ratios. Beginning with the conceptual framework of how data driven decision making can contribute to the operation of the library, the study will also provide concrete examples of how to analyze data from an Integrated Library System (ILS). Data will be presented for the case study of Gumberg Library at Duquesne University. The study hopes to address a perceived gap in the literature that percentage of users accessing a collection is often not considered in the analysis of circulation data.

Objective – To apply the principles of evidence‐based librarianship to the decisionmaking process regarding the cancellation of print serials.Design – Quantitative analysis of local and national data from various sources.Subjects – Data sources included 1249 current unbound print journals, 3465 Medline‐indexed electronic journals, statistics from the Association of Research Libraries and American Association of Health Sciences Libraries, as well as traditional library statistics.Setting – The study was conducted in the Yale University’s Cushing/Whitney Medical Library located in New Haven, Connecticut U.S.A.Methods – Several sources were targeted for data. A three‐month periodical usage study of the current issues of the library’s 1249 actively received print titles was undertaken. Excel‐generated alphabetical listings of titles were used by shelvers to indicate, with a check mark, which issues were shelved during a specified week. The workflow was adjusted to ensure only items under study were counted. Signs asking patrons not to re‐shelve journal issues were posted. Usage data were collected weekly and entered into an Excel spreadsheet where the total use of the journals was tracked. In‐house circulation, photocopy, and gate count statistics were also used. In addition to the survey, SFX statistics for the library’s electronic journals indexed in MEDLINE(3465) were gathered during the same 3 month period covered by the print usage survey. MEDLINE was chosen as the delineating factor to ensure consistent subject coverage with the print journal collection. For perspective and trends, statistics from the Association of Research Libraries and the American Association of Health Sciences Libraries were considered.Main Results – Based on the study’s findings, 53% of the print collection (657 titles) received no use during the study period; 7.1 % (89 titles) were used more than once per month; and 1.28% were used one or more times per week. Further, only 10% (125 titles) of the collection represented 60.7% of the total print collection use. There was also a direct correlation between the drop in patrons coming to the library and the decrease in print periodical use. SFX statistics revealed that of the 3465 MEDLINE indexed titles 14.8% (513 titles) were not accessed at all and 10% of the journals represented 56.8% of all SFX usage. These results were consistent with statistics from the Association of Research Libraries and the American Association of Health Sciences Libraries.Conclusion – Titles that were used the most in print were also used the most electronically. Further, the study revealed that print journals are used only a fraction as often as their electronic counterparts.Indeed, in both the case of print and electronic journals the largest use came from a small number of subscribed titles. Print collection maintenance is more labour intensive and costly than electronic. Consequently, resources spent supporting 53% of the print collection that is not used seriously impacts efficiency. With constraints on acquisitions budgets, funding unused collections does not make sense. Examination of the print serial collection is only part of ensuring effective collections.A s this study has indicated, unused electronic titles are also a drain on resources and further analysis of electronic packages is warranted.

The goal of this study was to examine the collections of eBooks in Spanish provided by vendors of library resources to school libraries to determine if there are equitable offerings of eBooks in Spanish relative to the Spanish-speaking school population in the United States. The results of the study indicated that the top vendors do provide eBooks in Spanish, but the titles comprised a small percentage of their total collections and do not mirror national demographics. Research findings showed that with only one to three percent of eBook titles in vendor's collections available in Spanish, there is a lack of equity in Spanish language eBook titles compared to the national school population of10% to 17% Spanish speaking children with varying degrees of English proficiency. This lack of equity in Spanish eBooks available for school libraries will be of growing concern as demand for eBooks in Spanish increases with the growing Spanish speaking school population in U.S. public schools.
