Hi, I am Rudolf E. Ritter, a retired physicist PhD, leaving outside Geneva, Switzerland. As a bookworm I did not loan my books from a library but preferred to buy my own copies. Over  almost half a century quite a collection of technical and scientific books accumulated. Since not a single of my children is interested in keeping the collection and although many of the books are somewhat outdated, they are still classics and too good for the wastebasket, so I prefer to dispose of them through this website.

The prices are for the books to go, but are still negotiable, specially for large orders or for students on a limited budget. With a very few exceptions stated on the listing they are mint, but many have a name stamp on the front page. Some dust jackets have worn edges. By clicking on the cover pictures they can be enlarged.

Since all books are available as a single copy only no shopping cart has been designed. For purchases or more information please contact me by e-mail : info@techbooks.ch or write, call or fax:

Payment by credit cards (Mastercard, VISA or AMEX) can be arranged.

Shipment to anywhere in the world is possible. However, with Swiss Post rates and weight of the books as they are, the postage cost may be higher than the basic price of the book.

PS: More books will be added, the lists are not yet complete, so come back and check the site again later !
