The International Music Score Library Project (IMSLP) also known as the Petrucci Music Library after publisher Ottaviano Petrucci is a project for the creation of a virtual library of public domain music scores based on the wiki principle. Since its launch on February 16 2006 over 220000 scores and 21000 recordings for over 61000 works by over 7800 composers have been uploaded. The project uses MediaWiki software to provide contributors with a familiar interface.
