About Institutional Repositories
Institutional Repositories (IRs) bring together all of a University's research under one umbrella, with an aim to preserve and provide access to that research.
IRs are an excellent vehicle for working papers or copies of published articles and conference papers. Presentations, senior theses, and other works not published elsewhere can also be published in the IR.
Where can I learn more about IRs?
The Association of Research Libraries is a good resource for information about Institutional Repositories. The following paper, "The Case for Institutional Repositories: A SPARC Position Paper" by Raym Crow, defines Institutional Repositories and argues their merits within an academic institution.
