Was there ever a 'zine with a more tortured road than the Living Greyhawk Journal? The support magazine for the RPGA's Living Greyhawk organized-play (and a general magazine for Oerth content) started out as a standalone magazine, but was constantly set back by cost-cutting at Wizards of the Coast. First it was turned into a subsection of Dragon, then it was sent off to Paizo, then it was moved over to Dungeon (which now contained the RPGA's Polyhedron) and then it was killed entirely. Along the way the amount of content was decreased step by step ... though what remained was still high-quality Greyhawk articles.

Oerth Journal is a very long-lived digital fanzine that was created at the dawn of internet fandom by the Council of Greyhawk, an AOL-centric fan organization. They published the first 11 issues. Since then the magazine has gone through two other major eras, under several editors. The unifying theme has been a deep exploration of the World of Greyhawk. The modern magazine is available not only in PDF, but in limited print copies.

The current index is partial, covering Volumes 1-2 of the 'zine, not (yet) the Greyhawk Online-sponsored v3.

Threshold grew out of the Vaults of Pandius, the prime source of Mystaran lore on the internet. In its early days, it was edited by a rotating cast of international Mystara fans, each of whom produced a massive issue of Mystara content focused on a single topic. This allowed publication four times a year. In more recent years, a few editors have taken up most of the work, and the magazine has slowed down to 2-3 issues a year. Nonetheless, it remains an enormous source of Mystara lore produced on a regular basis.

Old-School Essentials (OSE) is a real success story in the OSR, as the B/X retroclone gained considerable attention and success starting in the late '10s. Carcass Crawler is the official 'zine for OSE, a small, digest-sized magazine filled with crunch about OSE. It publishes about once a year and is largely authored by OSE creator, Gavin Norman.

Gary's Appendix is a three-times-a-year fanzine whose primary inspiration is the AD&D Dungeon Master's Guide (1979). It's likewise intended to be a fun collection of "odds & ends" that can randomly provide inspirations to gamemasters. One of those bits of "odds & ends" is an ongoing bestiary, which reprints new OSE SRD entries in every issue, but complete with mythology, folklore, and other background ideas of the sorts that you won't find in an SRD. Generally, Gary's Appendix is meant to support not just any OSR game, but any FRPG.
