4+ gigs of old tube and electronic manuals most of which are new in terms of scans of material I have never seen in electronic form. This guy has done a ton of work creating the PDF files.. ....................................... Preserving the Knowledge of the Ancients I've found that most of the technical books published before about 1964 never had their copyrights renewed, so now are in the public domain. So I am endeavoring to digitize and post some selected books relating to the "vacuum tube age" of electronics here. Many - maybe over half now - of these books were scanned by other people and contributed for me to post here. Many, many thanks to all the individuals who have helped out with this endeavor. I find that I do not have much time to scan books these days - the demands of the "day job" have increased much over the past few years - so I'm not doing a lot of scanning myself. If you have material that you would like to contribute, please send me an email. Technical books online

Yep. The thing is that most of those books are very old and of interest to the guys that still use what amount to "vintage" gear. Anyone interested in resurrecting antiques (or radio history) will be all over that listing. Serious kudos and full marks to the guy that scanned them in, obviously a labor of love.
