It has been a while since anything new was posted by me. But many good natured people have invested their time and efforts to keep the book coming. This post is for bringing forth those contributions and contributors. Chances are that many might not know about these books as the links were posted in comments of various other posts. Hence this short post. Detailed posts with contents, info etc. will follow later. And please do add more links. Apologies for mistakes and omissions, please let me know if I have missed any.
