Welcome to History in Writing. We specialize in Old Paper Collectibles of Books, Catalogs, Manuals, and Reports. We have a vast inventory of thousands of Technical Reports and Studies done by large and small Engineering Corporations from the 1940's to 1970's with some being newer. A long with the Reports we carry a vast inventory of Technical Books and Manuals on Engineering, Electronics, Microwaves, Antennas, Vacuum Tubes, Radios, Computers, Tools, Geology, Astronomy, Medical, and so much more. If it's Technical we'll either have it or try and find it for you. Our Catalog Inventory is quite large and includes: Coins, Tools, Electronics, Clothes, General Products, Science Instruments and more. Last but not least we also carry postcards, art, lithographs, advertisements, magazines, trade cards, and more. We are always listings new items in our Ebay Store from Collection Purchases of former Engineers. So keep checking back in as we only have about 10% of our Inventory currently listed.
