A central mission of Columbia University Libraries (CUL) is to make its collections available in support of research and scholarship by members of the Columbia University community and others. In order to support research and scholarship, CUL seeks to reduce or eliminate restrictions for the research and educational uses of the CUL collections, including the reproduction and publication of materials found in the collections. However, CUL and users of the Libraries must respect copyrights and other legal rights held by other parties that may affect the use of materials in the collections. Therefore, CUL provides services on the following terms for purposes of supporting teaching, research, and other scholarship. This statement applies only if the use of materials is principally for research and scholarship. Uses that are principally for commercial purposes may be subject to separate agreement between the user and the specific Columbia library holding the materials of interest.
