Scribd has a number of books (not downloadable, but just as useful). If you're visual, check out the "Head First" titles.

Or use google.

And there are torrents, etc.

Or, just buy it from Amazon, BookPool (well that used to be a better deal years ago), etc.

(Don't do anything illegal. Pay for what you read, otherwise good authors won't write anymore.)
