Libgen/zlib (zlib is basically an expanded fork of libgen) are pretty good for books - only issue is restrictions on downloads (and they've been getting harder to access due to the guberment cracking down on evil pirates). It probably has a lot of content others don't- MAM for example has a "banned authors" list. A combination of ABTorrents, MAM & Zlib will probably cover your bases.
