May I use Columbia's libraries if I am not a student, professor, or staff member at another academic institution?
If you are a resident of New York City or Westchester County, check with your public library. If your public library does not have the specific title or material you need for your research, obtain a yellow title Metro referral card from your public library. This card will give you a one-day pass to Columbia University Libraries. The Columbia libraries do not accept blue subject Metro referral cards.
