I'm sure that a lot of people are frustrated because they cannot read a posted book on their Kindle, Ipad, or other reading device. There is an answer. Go to Calibre at
http://calibre-ebook.com/, and download and install their program. This program is capable of changing any book format, such as .pdf, to any other format such as .epub or .mobi. Personally, I have a Kindle, and not only does it convert my books to .mobi, but it delivers them right onto my Kindle without any intermediary steps. I don't know how it handles other tablets, but I am pretty sure that for Ipad owners it will convert your books to .epub, then send them on to ITunes.
