Explore col­lec­tion guides, find­ing aids, and records to locate mate­r­i­al in the Organ His­tor­i­cal Soci­ety Archive.

Print­ed mate­ri­als are housed in cli­mate con­trolled rooms at Stoneleigh, the for­mer estate of the Haas Fam­i­ly in Vil­lano­va, Penn­syl­va­nia, as well as our off-site repos­i­to­ry in Warmin­ster. Spe­cial Col­lec­tions pri­mar­i­ly con­sists of the archives and busi­ness records of numer­ous Amer­i­can organ builders.

Processed Spe­cial Col­lec­tions may be con­sult­ed by appoint­ment in the OHS Library at Stoneleigh. Scans of processed mate­ri­als may also be request­ed by inter­li­brary loan or by con­tact­ing the archivist direct­ly via phone or email. Access to unprocessed Spe­cial Col­lec­tions is restrict­ed. The staff pri­or­i­tizes pro­cess­ing of col­lec­tions based on user inter­est, instruc­tion­al and pro­gram­ming demand, and resource and staffing availability.
