@v555: Thanks for the add-on, buddy. The more, the merrier.
I also encourage any of you who have additional sources (that are absolutely no-cost to download, bug or virus free and with decent to great topics) to share them. You can add right to this post if you want to.
@fjohnson59: Thank you again (I sent you a PM) for your kind words and all those wonderful reps.
Now, I'm off to look for something else to share.

Awesome share max reps added
Thank you so very much Layna61524.
Also I would like to add my favorites
Code:
http://libgen.io/
http://libgen.pw
Still not sure if they are the same, but they have different layout, and sometimes it happens to me that one site does have the book I want, the other doesn't.
Zajko: I remember including libgen.io in the original post but libgen.pw is a helpful add-on. I think the different extensions denote country origin. At any rate, thank you for contributing to the thread.

You Rock layna61524 - You are one of the main source for everything good and helpful here @ BBHF - Many Thanks 
The Libgen sites are the feed for Bookzz and Bookfi. You can skip limited downloads and/or paying a fee if you just go straight to Libgen. That's what I do :)
@Tisane: Thank you for your comment/advice. I rather like libgen.io ... it's one of three sites I go to for most of the ebooks I share here. The others are book-ok.org and one that escapes my memory at the moment.
By all means, if anyone has additional resources to share, add 'em on! The more, the merrier.

Just checked and libgen is also feeding {{{Blocked by Omni Potens, reason: reports from LEGIT GB STARTER}}}.org.
Excellent infos as usual - REP + :)
