When I discovered the OSR in December of 2010, sometimes I found it difficult to keep up with all the acronyms in use. B/X, OGL, FLGS, and on and on. It took about a month before I knew my way around the acronym block, so it were. So, for the newbies out there in teh interwebs, here's an Old School Renaissance Acronym Glossary & Dictionary, O.S.R.A.G.D. for short, since acronyms seems to be in fashion!

Blue Box - The first Basic D&D set, published in 1977 and edited by Eric J. Holmes. Covered levels 1-3 and was more closely related to Original D&D than later sets. Also the only edition in which the magic-user spell Magic Missile required a to-hit roll.
