OHS publishes its journal four times a year. The Tracker includes news and articles about the organ and its history, organbuilders, exemplary organs, regional surveys of instruments, and the music played on the organ. The emphasis is on American organ topics of the 18th, 19th, and 20th centuries, and there are occasional articles on European topics. Most issues run 32 pages with many illustrations and photographs, and at least one annual issue is published in full color.
Membership in OHS includes a subscription to The Tracker. Institutions may subscribe to The Tracker without enrolling as a member at the same rate as Regular membership.
