OAIster is a project of the University of Michigan Digital Library Production Service. Our goal is to create a collection of previously difficult-to-access, academically-oriented digital resources (what are digital resources? why is the "freely-available" designation gone?) that are easily searchable by anyone.

OAIster will NOT be updated for the remainder of August. We will be performing our bi-yearly full re-harvest of all repositories, cleaning out our database, and sending much belated notices to repositories with technical or character difficulties. We expect the next update to happen September 1.

Well-behaved repositories (without XML or UTF-8 errors) are updated on a weekly basis on Wednesdays. All other repositories are updated the first week of a month.

8,857,208 records from 680 institutions

We are also committed to improving our service -- you can view our future search improvement plans.
