The full-time law library faculty members are here to help you with your substantial writing!
Make an appointment for a research consultation by emailing reference@law.byu.edu (or the individual email of the specific librarian with whom you would like to meet). Include information such as your availability for an appointment, your topic and thesis, which class it is for, and who the supervising faculty member is. Then, the librarian assigned to your appointment can prepare beforehand.
Research consultations generally last 20-30 minutes.
