CLIO Open Data | Columbia University Libraries

"In an effort to further support the wide variety of research and experimentation happening around open library data, the Columbia University Libraries has made our catalog data open and available for download. This data represents the bibliographic and holdings data stored in our Integrated Library System and accessible through CLIO, the Columbia University Libraries Online Catalog. The public discovery interface for these records can be found at http://clio.columbia.edu/catalog.

These catalog records were created, modified and managed over time, according to different cataloging standards and rules at a variety of developmental stages. As such, their quality and completeness will vary as a result of changes of practices and record sources. With this in mind, we offer this data in its current state, without remediation or review. Please read the information below for further details on the formats, currency and structure of this data. Note that this dataset does not include records from the Columbia University Law Library Catalog, and that some sets of vendor-supplied records were removed from the open dataset at the request of those vendors...."
