If there are no such plugins, then, I'd like to create one for me :
I have a forum related to books & reading. I'd like to have a download section where books can be shared easily. Only public domain books & no piracy. I will just share direct download links of FeedBooks or Gutenberg [if that is illegal, then I will host them on my server]. It must be easy for admins to add books.
For example, feedbooks urls are like this :
Directs to page : http://www.feedbooks.com/book/1
now append .jpg, we get a cover : http://www.feedbooks.com/book/1.jpg
appending epub, mobi or pdf gives download link : http://www.feedbooks.com/book/1.pdf
OR the official resource manager can be used for this ?
