Eguild has a three-tier purpose. We want to protect author's rights, to promote epublishing in general, and works of our members specifically. No it's not. There's also EPIC, which I also belong to, but it's set along somewhat different lines. EPIC doesn't have a legal defense fund for authors.
EPIC seems more about sharing information, rather than protecting rights.
EPIC also believes in promoting epublishing as an industry. My biggest concern is the entrance of the publishing giants into the world of epublishing. Fifty years ago, the publishing houses cared about the craft of writing. Today they are all owned by huge international corporations. They only care about the bottom dollar, which is why so many books are so repetitive.
