Institutional repositories: assessing their value to the academic community Rowena Cullen and Brenda Chawner Victoria University of Wellington, Wellington, New Zealand Abstract Purpose – The purpose of this paper is to investigate the development of institutional repositories in New Zealand, exploring factors affecting the adoption and success of institutional repositories from the perspective of the library managers who established them, and from the perspective of the academic community. Design/methodology/approach – Data from a series of interviews with library managers are compared with the findings from a randomised national survey of academics. Findings – The responses of the library managers suggest that they are positive about the value of their institutional repository, and the progress made towards recruiting content for it. Data from the survey of academics indicate that academics have been slow to embrace the concept of institutional repositories, and show little interest in using repositories for increasing the accessibility of their own work, or to access the work of others. The number of deposits remains low, mirroring patterns throughout the world, and subject or disciplinary repositories appear to have greater value to the academic community. Practical implications – The future long-term sustainability of institutional repositories depends on gaining a stronger commitment from the academic community, or developing different goals, against which their success might be measured. Originality/value – The study is the first random survey of academic staff across all disciplines, and an entire country, and the findings have a very high level of generalisability.

Systems for distributing paper pre-prints by mail or facsimile were clumsy and slow, and researchers found it difficult to keep up with new developments in their fields. In the early 1990s, the rise of the internet made other communication and publishing options possible, starting with e-mail distribution, and then moving to the world wide web. The first web-based preprint server, arXiv, developed at Los Alamos National Laboratory in 1991, was initially used for physics pre-preprints, and has subsequently been extended to include aspects of mathematics, computational linguistics, and neuroscience. Other disciplines subsequently adopted the arXiv model, the best-known examples of which are economics (EconPapers), and cognitive psychology (CogPrints). At the same time, journal subscription costs were increasing significantly, particularly in science and medicine (White and Creaser, 2004). Many libraries responded by cancelling subscriptions, and, as a result, researchers were losing access to The current issue and full text archive of this journal is available at www.emeraldinsight.com/1467-8047.htm IRs: assessing their value 131 Performance Measurement and Metrics Vol. 11 No. 2, 2010 pp. 131-147 q Emerald Group Publishing Limited 1467-8047 DOI 10.1108/14678041011064052
