Before informing Columbia Libraries, it is advisable to make one final search to confirm the borrowed material is lost.
You can make payments for lost materials at any library Circulation Desk by check (payable to "Columbia University Libraries", or to "Barnard College" if paid at the Barnard College Library) (see the List of Libraries page for contact information) or visit the Library Information Office, located at 201 Butler Library.
Please note that borrowing privileges are automatically suspended when a book’s status change to “Lost/Missing”. For books that circulate from 4 weeks to a semester, the “Lost/Missing” status is applied 45 days after the due date.
For additional information on blocks and fines, see Avoiding and Resolving Blocks and Fines.
Some libraries accept replacement copies. Contact the respective library for its replacement policy. See the List of Libraries page for contact information.
