Reference

Norris Medical Library librarians answer health sciences reference questions via chat Monday - Friday, 11am -4pm (see floating red bar in lower right corner). During those hours, a librarian can also be consulted in person by inquiring at the loan desk. Outside of those hours, loan desk staff will assist with queries when possible and refer questions to specialists when necessary. 

Email reference questions submitted to our Ask A Librarian form or sent directly to medlib@usc.edu will be answered within 24 hours Monday - Friday, and questions received over the weekend will be responded to the following work day. 

For more in-depth reference consultations, request a reference consultation.

For reference questions outside of the health sciences, see USC Libraries Ask Us page.
