A Digital Archive Collection of rare and hard-to-find
Bell System Historical and Technical Documents


This Site represents our continued efforts to preserve some of the historical Bell System documents in digital format and to make these hard-to-find documents available to historians, collectors, students, teachers, hobbyists and other non-commercial, non-profit users.  The files on this Site are for historical archive purposes and use by collectors of old Western Electric telephones to repair and test phones in their collection.

If you are looking for technical information (like schematics) of Western Electric phones, check out the Bell System Practices (a.k.a., BSP's) page on this Site.  You'll find two complete Bell System Practices manuals on payphones as well as sections on phones found in homes and offices during the last few decades of the Bell System.
