I found a couple of great sites for indie publishers.
This one is by Joel Friedlander. It has not only won awards, it has resources on learning from others, on Social Media, on the pros and cons of indie publishing and more. Check it out here.
This one is by CJ Lyons has a ton of resources. Everything from cover art, to a tool box, to 4 pitfalls to avoid. Check it out here.
Jane Friedman has a great page on resources. From getting started and fighting self-doubt to News and trends. Check it out here.
Wise Ink blog has a great page full of resources for indie authors. Check it out here.
Hope these help! 🙂
