Ok, so, I don't usually link-bomb, but this site is worth it if you're a writer. This is a great resource!
'My Perfect Pitch' is run by author Brian Grove, who has spent, what seems like, many hours compiling an insane database of publishers. And, these are publishers who are CURRENTLY accepting submissions, and covers all genres. The site doesn't contain any self-publishing or vanity companies, and is a genuinely FREE resource.
There is also a heap of information about the writing process and how to go about getting your book published. Brian has put so much work into this site to share his expertise with US! So, thank you, Brian. :)
