Here’s the latest list from Matthew Carpenter, legendary Mythos reviewer.  He updates this list twice a year.  Please fee free to update or add to this list by commenting below.  I copied and pasted this from his Word document, so it might not format the best here, but it’s very useful information, regardless.

Matt Carpenter document follows:

Forthcoming Mythos update!   If I can, I am attaching a link to the latest information.  Of course corrections and additions are welcome.  With the pace of publication and myriad small presses I despair of keeping track of everything.  There is a lot of self published drek as well as e-pub only stuff coming out unannounced.  With my hectic schedule I can’t keep up.  I still have about 10 GREAT books to read and review, as I was until recently all gummed up with The Yith Cycle.  Please attach corrections.
