, sorry for my english
I am new here, and this it's my first small contribution with this site.
In the webpage of Gigapedia, http://gigapedia.org
there is a huge books colections of any type of topics. Particularly in electronics area, are 569 books of many many topics.
This is the catalog:http://gigapedia.org/browse.category:24,page:1.html
Only you have to create a user count, then click in the book do you liked, then click in the "link" seccion, and automatically the page show you where's the book housed, usually is in rapidshare or any other site.
I hope that they will be useful.
PS: Maybe this post can be placed in the other sections, to share with everyone this link.
