OSRIC, short for Old School Reference and Index Compilation, is a fantasy role-playing game system. OSRIC is a recreation of Advanced Dungeons & Dragons, and one of the most successful retro-clones.:366 OSRIC describes itself as "a compilation of rules for old school-style fantasy gaming...intended to reproduce underlying rules used in the late 1970s to early 1980s". OSRIC uses the Open Gaming License and the System Reference Document to create a new artistic presentation of the underlying rules set.
The purpose of OSRIC is to provide publishers with a tool to legally produce gaming materials compatible with the non-copyrightable aspects of the underlying rules set. Gaming materials described as OSRIC-compatible alert potential users those materials may be compatible with Advanced Dungeons & Dragons. More than 20 different publishers have produced more than 100 products branded as OSRIC-compatible.
The initial version of OSRIC was released in 2006. The OSRIC rules are free to download from the game's site in PDF form. In June 2009, hard copy versions of the rules became available from the Lulu Print-On-Demand service in 4 versions: hard bound in black-and-white, hard bound in color, paperback and paperback economy. Additionally Black Blade Publishing and Usherwood Publishing together put out a hard bound print version with extra art and indices not appearing in other editions.
