Literature available in hardcopy only.

Why? Much of our library was formed as we acquired stacks of undistributed re-issues many years ago. Some we had made with huge bus size printers in the 70s and 80s.  We are designated custodians for Graybar Inc, UL Labs and various retired engineers. While not usually original - you will find our reprints can be antiques as well! We often only have 1 or 2 copies in stock, as they are unearthed and listed as we go.  Often bound in staple, cloth, or brass - sometimes dusty! For 35yrs, we have collected and maintained archives of all the best and rare audio. 100's upon thousands have been invested over the years. From A-Z. Encompassing giants like Western Electric / ERPI / Bell Labs , Langevin, GE  and RCA. Extending into the consumer HiFi and  DiY era. 1930s to 1980s. Acrosound, Jensen, and Altec; to many to list! Mailed promptly USPS Priority Mail Worldwide with tracking. Quality content guaranteed.
