Library Essentials and Workshops
Library Essentials are short video tutorials to help you with your research. Many of the Columbia Libraries offer hands-on research skills workshops to help you make better use of the libraries.
Finding Library Materials
The Libraries' website is a gateway to collections and services, including access to a wide variety of databases and e-journals.
CLIO is the online catalog for the Columbia, Barnard, and Union Theological Seminary libraries. Search CLIO for print and electronic books, journals, videos and dvd's, sound recordings, newspapers, and other materials. Use CLIO to request materials from Offsite, renew books, place recalls and holds.
Borrow Direct enables you to borrow books directly from six other Ivy League university libraries in the event the book you need is either unavailable because it is circulating; or is not owned by a Columbia University library. Typical delivery time is 4 business days.
Interlibrary Loan is the service to use for all other items not available through Borrow Direct, such as journal articles. Delivery time may be within 1-2 days for articles; 2-3 weeks for books.
