Starting in 2015 I maintained a list of publishers of weird fiction, literary horror, or mainstream fiction that occasionally handled either. That list stayed current for a few years, but updates gradually became less frequent, and it became ever more out of date. Many people have used it over the years, but my interest in refreshing it has gone. If you’d like to save the links I had posted for your own purposes, there’s a copy over on the Wayback Machine.
These days, seems like more people get their market info from social, or from those folks who do regular submission roundups, like Eric J. Guignard or Gwendolyn Kiste. Likewise, check out Ralan.com, lists from writer’s organizations (SFWA, AWP, etc.), The Grinder, etc. Cheers!

It got much use, and will be missed.
Thank you for saying so. I’m glad it met some needs while it yet lived…
J.T. Glover, that octopus is eye-catching. I appreciate your list. Recently, I have developed a fascination with Octopuses, and it’s NOT Octopi. Thanks for your list!
