Here’s a link to Feedbooks – a simple way of taking site/blog/twitter or any content from an RSS feed and quickly turn it into an archivable or eBook reader friendly format. There is a good description of how to do it here, including useful info on how to go via Yahoo Pipes to reverse the order of your posts.

As a test, here is a link to a PDF of my posts on this blog made with Feedbooks. It took less than 5 minutes and the front page could be easily replaced.
