And yet another nice wad of technical ebooks for those wanting to know Watt's Watt about electronics, at least till the mid-1950's. http://www.tubebooks.org/technical_books_online.htm
I've downloaded so many torrents of PDF's but idk i can't seem to concentrate while reading them on a device, i need a good old paperback. If only i had a printer and enough ink to print several thousands of pages lol.
I have the same trouble really, and mostly with PDF's I tend to find the material I want to dig into deeper and print the few relative pages as needed. I'm mostly past the stage of learning the fundamental principals in the various areas that hold my interest so the books are more as a supplementary reference for me. But lucky for me theres Amazon, Public Libraries (St Louis Downtown branch mas an AMAZING co9llection of antiquated book on science and may be the first place I head if the shit ever does get around to really hitting the fan (Short of Zombies, then it's Gun shop followed by Walmart) used book stores (some still exist. lol) and other places like www.lindsaybks.com for my hard copy needs.
Ohhh this is the four hundredth time today that I kicked myself for not replacing the ink in the printer =D Thanks for the links!!!!
