The Portsmouth School Old Timer's Club held a picnic every year for alumni of Portsmouth School in the Portsmouth area of Portland to socialize. Collection includes administrative records; member lists and member list books; a scrapbook; an account book; a minute book; correspondence; receipts; and promotional mailings and flyers.

This collection reflects efforts by the Society of Oregon Composers to gather a library of Oregon musical compositions, and to promote and support musical composition in the state. The collection consists primarily of musical scores for voice, piano and strings (1902-1941), with other materials relating to the music library, membership in the society, and competitions.
