One of the websites my company created and continues to manage is Architecture & Governance Magazine, a community site with several hundred articles on something called Enterprise Architecture.  They recently asked us if we knew how to create an eBook out of their monthly PDF of their new articles.  "Not a clue!" I said, resisting the urge to lie. "But I'd like to learn how."  So I spent some spare hours over a couple weeks and dove into it, eventually producing a very nice looking eBook. I wrote about the process over on our corporate site, if you are interested in learning how to do it yourself.
