If you visit no other writing resource, visit this one. Preditors and Editors. The absolute best resource for both new and experienced writers. Why, you ask? It lists almost every possible agent/agency and publisher you can think of and evaluates them. I've talked about this before, but I must mention the site again. Must! It is that important.
When you start this journey, like me I assume, you have trepidation and unbelievable uncertainty. What am I doing? Can I really do this? Will I be taken advantage of?
This last question is what led me to Preditors and Editors. I could not believe someone had taken the time to develop the site. To do the research required and to put himself out there for the protection of me and you. It was created by David Kuzminski, who recently passed away, and then taken over by Dr. Andrew Burt. Both have seemingly been where we've been. Possibly experienced the same trepidation and uncertainty. What an ingenious idea.
Check it out. Right now. This very minute. You will not be sorry.
