One of my blog readers from Europe is preparing to submit her first book to agents and publishers. She has plans to attend the International Book Fair in Germany in October, but she wanted to study up before then. She asked for my best bets in books, blogs, and other resources.
I'm always delighted to share my favorites. I have to credit friends, colleagues, students, and other writers in the trenches of submission for most of these resources. Anyone who's been through it knows how challenging the whole infuriating, wonderful, discouraging, illuminating process can be. It helps so much to study up beforehand. Be not surprised or unprepared--you'll kick yourself and you'll probably lose any future chances with that particular agent.
So here's the best I've found, thanks to many helpers over the years. I've used all of these myself.
