There is a D&D product list available via my Complete D&D Monster Index page which includes the release years and months (where known) for all TSR D&D products. Here's a direct link to the file in case you don't feel like more than one click.
I work on the main index of monsters (and thus also update the product list) on a fairly continuous basis. I've been running a little behind with 4e additions though (looking at you MM2, E1, E2 and Eberron Campaign setting), so I haven't published an updated version since the end of last year. Once I'm all caught up again in a month or two, I'll most likely update the files on the web site again.That's ultra spiffy, Echohawk.How often do you update it?
Thanks grodog. Those dates aren't perfect -- especially the older ones -- but I tried to get them as accurate as possible based on available sources. The spreadsheet has been mentioned before on the Acaeum forums, and I explained my methodology for establishing the dates in a little more detail there.Thanks Echohawk! The file looks pretty interesting and thorough. I've bumped an old "release dates" thread on the Acaeum @ exact month of release of old TSR items? and pointed to your file, to see if folks can shed further light on your dates.
