I’ve put together a javascript framework (a very simple one) for a cooperative add server for indie authors. The example on my front page just has my books right now, but I expect that to change. It’s going to need a better data organization than instances of an object (probably xml). Anyway some of my friends will try it out.
It can link to servers like Iauthor or goodreads and lets you handle different vendors (both Amazon and smashwords work). I like the idea of using Iauthor because you can get statistics from them.
