You will run into copyright issues on some of the items mentioned. Most ammo collector authors are not cooperative in having copies made of their works in my experience. I have hundreds of ammo references digitized on CDBs and some mentioned I have tried to get as well without success. GOOD LUCK !
I have tried to have the Tear Gas book reprinted or get the rights to digitize but they will not cooperate. Why? No idea. Ironside publishing which has published the newest editions of Swearengen’s books have also tried - no luck. Limited market for that book in any event.
Dan Kent, same way. He does not plan to reprint his 7.9 book but doesn’t seem to want anyone else to publish it either. I have tried as have others. There is a market for that book.
Dr. Windisch’s book 1 on the 7.9, ditto. A classic which everyone should have but he says no.
Dr. Regenstreif was more forthcoming and his first book on Soviet ammo has been digitized and I hope to be able to put his headstamp books on a CDB as well. HIS NEWEST BOOK ON SOVIET/RUSSIAN AMMO IS EXCELLENT especially if you can read French. The photos are worth the price even if you do not.
Good luck with your copies but for me PRINT IS DEAD. CDBs are much easier and faster to publish.
