IMSLP

Reopened (June 30, 2008)

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 220,000 scores and 21,000 recordings for over 61,000 works by over 7,800 composers have been uploaded. The project uses MediaWiki software to provide contributors with a familiar interface. Since 6 June 2010, IMSLP has also included public domain and licensed recordings in its scope, to allow for study by ear.
