IMSLP/Petrucci Music Library

Free public domain music scores and/or sheet music library. [06june09]

The Petrucci Music Library plans to create a virtual library containing all public domain music scores and/or sheet music, as well as scores from composers who are willing to share their music with the world without charge.

Online since February 16, 2006, the database now includes 15,574 works and 29,641 scores, the website is now translated in 13 different languages and provides "discussion" pages and forums for interactive discussion with the community. Users can easily browse the score database by composer name, time period, genre or instrument. Based on a simple Wiki structure, the project is also asking for people contributions:

"You can contribute by simply participating in the growth of this wiki by sharing your knowledge in music with others. If you have public domain sheet music on your shelves or hard disk, consider sharing it with the rest of the world by uploading it to the Petrucci Music Library! You can also help by importing public domain scores from other websites."

Also, the IMSLP Community Project plans to acquire collections of works from inactive archives, scan or upload works from private donations, or other tasks. One of the current projects is the Orchestra Parts Project. Completed projects include the acquisition of the bh2000 archive, the Gutenberg score archive, and the Bach-Gesellschaft Ausgabe.
