OAIster (A union catalog of digital resources)

OAIster is a union catalog of digital resources that provides "one-stop shopping" for academically-oriented digitized materials. OAIster provides access to the resources in nearly 900 collections world-wide by harvesting their descriptive metadata using OAI-PMH (the Open Archives Initiative Protocol for Metadata Harvesting). The digital resources include digitized (scanned) books and articles, born-digital texts, audio files, images, movies, and datasets. (Updated approximately twice a month)
