Dagan Books is accepting submissions for Bibliotheca Fantastica until the end of March, 2012:
What we want: Stories having to do with lost, rare, weird, or imaginary books, or any aspect of book history or book culture, past, present, future, or uchronic. Any genre. Although the fantastical is not essential per se, stories should evoke a sense of the fantastic, the unknown, the weird, wonder, terror, mystery, pulp, and/or adventure, etc.
They pay 2 cents a word, up to 10,000 words.
So far, the best subs for BF have mostly been wry and/or metafictional, which has been fun to read. I would love to see more adventure, more pulp, more suspense, more passion, more emotion.
