I too would not mind a new 4E version. AV (Adventurer’s Vault), FR: CG (Forgotten Realms Campaign Guide), and some others in 4E. Along with the new books coming out for it too. Might be worth our while to make a list.
We could separate it into different sections such as Universal (DMG, MM, PHB) and then break it down into books for each version (3, 3.5, 4, w/e else versions, I see different 3.x and 3.75 plenty) and terms for each version (Like PC for prestige class and PP for paragon path)
Just my two cents, but I would be happy to look through the books for acronyms and help post them in some semblance of organization
