Purcell upon the donation of the Vahdah Olcott-Bickford Collection to California State University, Northridge. Originally housed in the Music Department, IGRA now holds one of the world’s largest collections of guitar sheet music, especially works for solo guitar, ensemble pieces for multiple guitars, and ensemble pieces for guitar and other instruments. IGRA also holds accompanying resources documenting the lives and careers of numerous guitarists and professional associations, as well as other guitar-related materials.

Collection Strengths

IGRA holdings include sheet music, periodicals, correspondence, photographs, audio recordings in numerous formats, printed books, and other materials.

Selection of Materials

Library materials are designated for IGRA when their subject matter, format, age, scarcity, or other unusual characteristic merits their inclusion. The Special Collections and Archives Librarian determines what materials shall be placed in IGRA. The librarian may also confer with members of the Library faculty regarding the transfer of items already in the collection that meet these criteria, and for the purchase of new materials.
