This search engine will lead you to digital resources previously "hidden" to users behind web scripts.
Most search engines like Google won't pick up these digital resources. Robots used by these search engines don't dive "deep" enough to retrieve this information. Therefore, these digital resources are often accessible only to those who know where to look for digital repositories and developing digital collections.
OAIster is a project of the University of Michigan Digital Library Production Service. Use it to search nearly 700 institutions including a total of 8,754,367 records. These records are a part of previously difficult-to-access, academically-oriented digital resources. This service was built through a collaboration with the University of Illinois at Urbana-Champaign and encompasses a broad collection of resources with no subject limitation.
