Butler Library’s primary purpose is to support Columbia University’s educational and research programs.  Butler Library may also serve the needs of local, national and international communities when doing so does not detract from the library’s primary purpose. 

Access to and use of Butler Library is a privilege extended to Columbia University faculty, students, staff, alumni and sponsored guests.  Access to Butler Library’s physical spaces, services and resources by others is normally limited to specific and limited access to library collections or resources.

Current Columbia University faculty, students and staff have priority access to Butler Library physical spaces, resources and services.
