Poets and Writers classified ads are a good source for finding all manner of anthology calls from non-fiction to poetry http://www.pw.org/classifieds While looking around on the site I found an anthology call from Bona Fide Books http://www.bonafidebooks.com/tahoe-blues The anthology is called Tahoe Blues and they're looking for submissions of 500 words or less in any genre with a Lake Tahoe theme. The deadline is May 1. I couldn't find any mention of pay so that is something you'll have to find out from the editors.
newpages.com has posted their January call for submissions list. http://www.newpages.com/literary/submissions.htm One that might be of interest here is from Press 53 for the new Surreal South anthology. http://www.press53.com/SubmissionsSurrealSouth.html "Surreal South 2011: Ghost and Monsters" is looking for shorts of 1000 to 7000 words. Authors must be Southern and the work must contain surreal elements. The deadline is March 15. Pay is one copy plus $50 website credit from Press 53.
If you're a native or resident of Singapore. World SF is putting together an anthology of Singapore SF Stories with the theme Hybrid. http://worldsf.wordpress.com/2011/01/26/singapore-sf-stories-anthology-call-for-stories They're looking for spec-fic stories of 2000 to 6500 words with an April 30 deadline. This is a non-paying market, their purpose is to showcase sci-fi from Singapore writers.
And I found a new market source that I will be putting in the column to the right. The site is called Femministas and they showcase women's markets both fiction and non-fiction. http://femministas.blogspot.com/
