A new publisher (Tor), a new size (Trade Paperback), and Hartwell is the solo editor (no Kathryn Cramer).
There are four current Year’s Best anthologists (Dozois, Strahan, Hartwell and Cramer, and Horton). Prior to this there have been several other series, going back to the 1950s. Use the sub-categories under Years Best in the right hand column to browse these.
After two slightly slimmer volumes, #30 returns to a chunkier size – huzzah!
A few stories that don’t quite do it for me, but otherwise a great read.
Wow, I’ve read all of Horton’s 2012 volume in 2012, a big improvement over previous years.
A good range of sources covered, with three of the four major magazines getting a look in (no Analog), a couple of anthologies, and a range of online sources. Buy a copy for your bookshelf.
