I've finished compiling a list of all of the changes made to Holmes Basic Rulebook (a comparison of the first and last known printings):

List of changes made to the Holmes Rulebook

To make changes easier, I'm just posting it in one place - the Dragonsfoot Classic Forums. Feel free to discuss it here or there. Any corrections, comments, feedback are most welcome.

Thank you! You certainly can use it for the Acaeum. I created it with the idea of submitting it here & was actually just looking at the submissions page for the email address a few minutes ago. I posted it over at the Dragonsfoot forums because they generally discuss more of the minutiae of rules changes with respect to gameplay.

I have the list in a Word document with more formating (bolding, italics, underline) that makes it easier to read, but couldn't figure out an easy way to convert it to the BBcode, so I just added a few tags on some of the headers. I can send you the Word Document, or you can just cut and paste it from the post, etc.

That's some quality research right there. Well done.

*bump*

I made a lot of revisions to this list (see the first post in this thread), including formatting (bold/underlining) to improve reading, and adding new content. I rewrote the introduction to list all six prints of the Holmes Basic rulebook (because the Acaeum entry only covers prints of the boxed set). There's now a comparison of the detachable REFERENCE TABLES. Thanks to jasonw1239 for providing a copy of the 1st print tables. There's a new Appendix D which lists all of the specific references to AD&D in the rules. (If you missed them before, Appendices A-C list all of the references to Monsters, Weapons, and Higher Experience Levels that are not described elsewhere in the rules). There are some miscellaneous new entries & comments that I've added throughout.

Foulfoot, feel free to grab a revised copy for the Acaeum.

You are quite welcome zhowar, I was glad to be able to contribute a little bit to the project.

It was appreciated. I actually meant to add your name to the list itself, in an acknowledgements section. I will do so in a future revision.

Here's what I discerned from the reference tables: (1st print / 3rd edition)
REFERENCE TABLES
Front (pg 47/47): Only changes from 1st -> 3rd are Halflings -> Hobbits in the Saving Throw table, and a Registered Trademark symbol after the "DUNGEONS & DRAGONS" logo.
Back (pg 48/48): WANDERING MONSTER TABLE matches respective edition (see above pg 10); in 3rd, CLERIC VS UNDEAD TABLE has revised notation for "Number =" (see above pg 12) and also adds "(use 2d6)" below title; each HIT TABLE adds "(use 1d20)" below title
