I ran across a great tool the other day that I thought I would pass along to all of you authors and publishers out there. It is called Issuu, and it is a Flash-based interface for viewing PDF files on the Internet. All you do is go to the website, set up an account, and upload a PDF file. Then, the PDF is converted into a Flash viewer that lets you "turn pages" and do other book-like things. The book can then be embedded on your website or blog.
I think this would be a great way for publishers and authors to make samples of their content available online in a nice, easy-to-read format.
