Given the current state of flux the publishing industry is in and with new opportunities for authors to take publication into their own hands opening up seemingly by the minute it might be a good time to provide links to some professionals who have tried to self- publishing. Here are a few links I found informative:
Aliette de Bodard is a multiple award winner and traditionally published author. Her thoughts on self e-publishing are here.
Patty Jansen is another award winning writer whose blog is a great source of information with many articles based on her own experience and those of her guest bloggers. Well worth a look.
Catherine, Caffeinated is the blog of Catherine Ryan Howard. She has wide experience in self publishing. Her blog posts on the subject are here.
This article outlines author Mark Edwards' choices and his reasons for the course he has taken.
Then there's this article about a different form of self publishing where a co-operative of experienced writers have banded together to publish their books and use their skills to make a professional product. The comments are worth looking at too, because there are others who are doing this as well.
There are many others, of course, some more reliable than others, but it's certainly worth searching.
