I love science fiction short stories. Some of the best SF I have read has been in the short story form. Right now I am reading a collection called Wastelands. So far I am really enjoying it. My only criticisms of it are that there aren't enough older stories and and that first one by Stephen King was just silly. Other than that it's been a fun read so far.
Today I did find a list put together by Jonathan Strahan of all the science fiction short story collections he could find that are coming out in 2008. You can view it here. There sure are a lot.
