Throughout his career, James K. Guthrie collected numerous musical scores. In 1974 he founded the Guthrie Music Rental Library and made his extensive collection available for rent in order to encourage musical performances.
Through the library, he provided scores and orchestra music to thousands of schools, colleges, and orchestras, including both major and new struggling orchestras, at affordable prices. He also acquired the library of his friend, James Dolan, librarian for the Los Angeles Philharmonic Orchestra. Later, Mrs. Louis Palange donated her late husband’s library to Guthrie, as did Mrs. Leo Damiani. The result is an extensive and varied musical library full of important scores, both well-known and obscure, that are still available today for rent.
