Rethinking the Subscription Paradigm for Journals: Using Interlibrary Loan in Collection Development for Serials

Authors : Gail Perkins Barton, George E. Relyea, Steven A. Knowlton

Many librarians evaluate local Interlibrary Loan (ILL) statistics in order to affect collection development decisions concerning new subscriptions.

In this study, the authors examine whether the number of ILL article requests received in one academic year can predict the use of those same journal titles once added to library resources.

There is little correlation between ILL requests for individual titles and their later use as subscribed titles. However, there is strong correlation between ILL requests within a subject category and later use of subscribed titles in that subject category.

An additional study examining the sources from which patrons made ILL requests shows that database search results, not journal titles, dominate. These results call into question the need for libraries to subscribe to individual journal titles rather than providing access to a broad array of articles.


Looking for the Impact of Open Access on Interlibrary Loan

Authors : Collette Mak, Tina Baich

The purpose of this paper is to analyze interlibrary loan (ILL) article requests for evidence of a decrease that could be attributed to the spread of open access. The authors collected and analyzed the interlibrary loan data of two Indiana academic libraries for requests submitted during October and November (peak ILL months) from 2006-2015.

The requests were assigned to one of four categories: general, humanities, social sciences, and sciences based on Library of Congress classification, and the relative age of each article was calculated, where the relative age is the difference between year of publication and year of request.

Assuming an embargo period of 12-18 months for traditional publications, a change in articles of relative age 0-2 would suggest that scholars were obtaining that material from other sources.

The authors then looked for trends that might indicate the impact of open access on interlibrary loan requests. This paper will present the results and discuss the other environmental factors that may influence the number of requests placed within a field of study.

The Evolution of E-books and Interlibrary Loan in Academic Libraries :

« As academic libraries add electronic monographs (e-books) to their collections in increasing numbers, they are frequently losing the ability to lend this portion of their collections via Interlibrary Loan (ILL) due to licensing restrictions. Recently, new options have emerged as alternatives to traditional ILL for e-books. These options introduce new opportunities for collaboration across library departments and within consortia. This article discusses the changing nature of resource sharing as related to e-books, examines e-book lending capabilities as they currently exist, and presents alternative models to traditional ILL, including short-term lending, purchase on demand and print on demand. »
