About Ask a Librarian Services

The Ask a Librarian services at Columbia University Libraries are staffed primarily by Columbia University Librarians during business hours Monday through Friday from 10 a.m. - 5 p.m.

Most evenings during the Fall and Spring semesters, (Monday through Thursday and Sundays from 5 p.m. - 9 p.m.) our chat services are staffed by library school interns from accredited Master's degree programs that include Queens College, the Pratt Institute, and Long Island University's Palmer School at C.W. Post.

Use of Ask a Librarian services is limited to Columbia University faculty, students, staff, and alumni; and to those with questions specific to the Columbia University Libraries, the use of its collections, and its policies. If you’re not affiliated with Columbia University, please direct your query to your local public, state, or academic library.
