Recently I started googling out old AD&D books, but I stumbled upon very strange mix-up in terms of edition naming convention. For example, the Wayne's Books listing of a later series of Greyhawk modules has most of the Greyhawk book covers, but strangely enough, many times newer books are named "AD&D" while older ones have "AD&D 2nd Edition" in the title. The same happens for Forgotten Realms listings, and other setting books too.
I've read somewhere that AD&D 1e and 2e had some small overlap in terms of releases, but it doesn't explain the scale of the issue and the examples below.
How am I supposed to know which AD&D books are actually for 2nd Edition, and which are for 1st Edition?
Even assuming the small overlap mentioned above and some reprints which I identified, I'm still finding books released 5+ years into the lifespan of 2nd Edition that still have the old 1st Edition logo.
Was the release schedule that insanely messy back in the days? Or did they drop the "2nd Edition" part of the logo for some reason? Or did something else happen there?
Examples of the problem:
- Greyhawk Player's Guide (1998): Not a reprint (at least not of anything I can find); nearly 10 years into the 2nd Edition lifespan but with a 1st Edition logo. Also released long after other Greyhawk 2nd Edition content which makes it even more odd.
- The Scarlet Brotherhood (1999): Also not a reprint; also has 1st Edition logo. Even Wikipedia says it's for 2nd Edition, though.
- TSR Silver Anniversary Collector's Edition (1999): On the first page, there is information that its content is updated for 2nd Edition, yet the cover still has the 1st Edition logo.
There are, of course, many more examples; the ones I found so far are mostly of setting-specific books (Forgotten Realms, Greyhawk, Dark Sun, etc.).
