Medford Library primarily serves the students and faculty of USC Lancaster and is also open to the public, high-school age and above.  Barcoded library cards are available free at the Library's circulation desk.

Most library materials and government documents may circulate from the library for a loan period of three weeks.  Fines of .25 per day per book apply to overdue materials.  Reference materials, periodicals, and audiovisual media may be used only in the library. A coin-operated photocopier is available.

Any patron needing a book, government publication, or article for scholarly purposes that Medford Library does not have in its collection may use the Library's Interlibrary Loan service to obtain the information from another library. See any library staff member for details.
