OAIster is a union catalog of digital resources from over 1000 contributors worldwide. Items include digitized books and articles, born-digital texts, audio files, images, movies, and datasets. Collections include theses, technical reports, research papers, and image collections. These resources, often hidden from search engine users behind web scripts, are known as the "deep web." This is the freely accessible version from OCLC.
