Dave Lull sent along a link the other day to the Independent Publisher, "the voice of the independent publishing industry". This online magazine celebrated its 20th birthday in 2003, and here explains what it’s all about.
The current issue contains articles like "Helping authors negotiate the tricky world of self-publishing contracts" or "From the trunk of the car to the big screen: self-publishing success does happen" (Eragon being the type-example of the moment). There’s a massive archive of past issues on the site.
There are various resources, such as a listing of books released by "independent, university, and self-publishers" to increase recognition, advice about how to sell more books, and a "share your story" archive. The organisation also sponsors the annual Independent Publisher Book Awards.
