Here are two anthologies closing end of October 2015, by Zombies Need Brains, which is:
a newly created small press owned and operated by Joshua Palmatier. It will start by focusing on producing professional-quality science fiction and fantasy themed anthologies, initially funded by Kickstarters. The intent is to produce two anthologies a year, then branch out into more anthologies and other stand-alone books once the press has gained its footing.
Calls are out for both their 'Alien Artifacts' anthology:
ALIEN ARTIFACTS is to feature stories where some type of left-behind alien tech has been found and how it may affect our society, our humanity, or the characters. It can be an artifact discovered on Earth in our past or during current times, OR PREFERRABLY, an artifact that we run across while exploring space in the future. I want to stress this: the story must feature an alien artifact (not an alien). Aliens can appear in the story, but the genesis of the story must be some kind of alien artifact. Stories featuring more interesting alien artifacts, and twists on how they are discovered or how they affect our society/humanity, while being set in the future, will receive more attention than those set in the present or past. In other words, we don’t want to see 100 stories dealing with an archeological dig discovering a long buried alien artifact.
And for their 'Were-' anthology:
WERE- is to feature stories where some type of were-creature OTHER than a werewolf is the main character. Werewolves can appear in the story, but they cannot be the main character or the central focus of the story. I want to stress this: the story must feature a were-creature! Stories featuring more interesting were-creatures, and twists on how they are integrated into the story, will receive more attention than those with more mundane creatures. In other words, we don’t want to see 100 stories dealing with a were-cat.
In both cases they "are looking for a range of tones, from humorous all the way up to dark"
Zombies Need Brains pays royalties of 25% of ebook/10% of trade paperback, split evenly between authors and editors, and 0.06 US dollars per word for Short Story and Flash Fiction pieces up to 7,500 Words. For each additional $5000 raised above the Kickstarter minimum of $10,000, they increase this advance pay rate by 1 cent per word (note: the advance is considered paid out if the Kickstarter funds, which it has by miles: https://www.kickstarter.com/projects/543968884/alien-artifacts-and-were-sfandf-themed-anthologies).
