Petrucci Music Library
The Petrucci Music Library is a wiki-based repository of musical scores. With a goal of creating "a virtual library containing all public domain music scores, as well as scores from composers who are willing to share their music with the world without charge," the project is quite ambitious. At present, more than 26,000 works are available in more than 66,000 scores and parts. Additionally, performers have contributed a number of recordings in MP3 format to accompany the scores. The collection is both browsable (composer, time period, nationality, or genre/instrumentation) and searchable (keyword, composer, or database index number). Scores are available in downloadable PDF format. Scanning quality is generally good. Metadata are acceptable but uneven across the database with some items described accurately while others lack authoritativeness and specificity. Because of its public domain scope, content does not necessarily reflect current scholarly editorial trends.
