Books, Books and ... Books

Plenty of E-books are available on the net, for free and for a price. This is an effort to identify those books that are legally free for download. Many a time such books are not available on the net in the format one wants; I have made an effort to convert these files to more reader friendly formats like Epub and Kindle. Should there be any infringement on Intellectual Property Laws, it is totally inadvertant. Please point out such infringements if any and the concerned file will be removed immediately.
