Camden Miniature Steam (from Somerset, UK) like to think that their 80 page Full Colour FREE Booklist is one that anybody with almost any form of mechanical interest should have - and a lot of their customers seem to agree.
It covers a wide renge of technical (mechanical, electrical etc) subjects, with many of the books being "hard to find imports". There is also a great selection of films on engineering, transportation and of classic films. They claim that many folk will be tempted!
The full list is shown on their website,
http://www.camdenmin.co.uk/index.html but they will be pleased to send you a copy (
it is FREE worldwide) upon request. If you place an order from their site, a copy of the catalogue will be sent automatically. And to place an order is very simple - just use the shopping basket facility and complete the Order Form.
PS I am not connected in any way with this company (except as a satisfied customer), but I thought that there may be some more folk who may be interested in this catalogue
