Hi, my first post here, hers a nice home page about electronics, and other fun information:
All about Circuits
You're right, this is an excellent collection of electronics books. Although it's very very comprehensive and I'd personally would've liked a more concise approach. I was actually going to post this myself but you beat me to it! :)
I have a recomendation, WinHTTrack website copier, a free tool which alows you to copy entire sites to your harddrive. You can then browse these sites offline and more important: if the site goes offline you still have your copy!
