Hrm. Seems I didn't trust my google-fu enough after some failed searches. More searching revealed a couple lists:

Guy, this spreadsheet of D&D products might help you.

Wow!

Out of curiosity -- and if you know -- how accurate are the months for the items? Do they track release month, first mention of the product in an advertisement, or something different?

They are supposed to be the release date of the product, and they are as accurate as I could make them when I was compiling the list. (Which does not mean that they should be taken as gospel!) For the later products (everything from about 1994 onwards) the dates should be pretty accurate. For older products, I tried to establish the release month based on Dragon magazine adverts, copies of old product catalogs and online research (go Acaeum!). Occasionally I was forced to guesstimate the release month of one module in a series based on the known release dates of others in the same series. And you may notice that some entries have a date 19XX-12-31. That means I couldn't narrow the date down at all beyond the release year.

If I was starting that spreadsheet again from scratch, I'd use three separate columns for the date, and include only confirmed date information (so where only the year is known, the month and day would remain blank). But that spreadsheet has grown organically over a couple of decades, so I didn't know that that would be useful when I started it

In case you are curious, that product spreadsheet is actually part of my larger Complete D&D Monster Index, which aims to be pretty much that

The date info makes sense. The monster index looks cool too!
