With Wizards reprinting the AD&D books, some new and old AD&D players will be looking for AD&D adventures/modules. One of our illustrious OSR bloggers assembled this AD&D module list (a Google Docs spreadsheet). It's a handy reference for anybody that needs a quick link to a level-appropriate 1e D&D adventure. Included are links to over 100 free and commercial adventure modules.
The AD&D reprints ship in April. Spread the word about this link (http://tinyurl.com/ADDmods), so everyone will be able to find the spreadsheet in a couple of months.
