"Members of the public are being asked to help describe 4,000 music pieces from the Bodleian Libraries’ collections, as part of a new project launched today. What’s the score at the Bodleian? (www.whats-the-score.org) is the first crowd-sourcing project undertaken by the Bodleian Libraries. About 4,000 pieces of popular piano music from the mid-Victorian period have been digitized and made available online. The music was mostly produced for domestic entertainment, and many of these scores have illustrated or decorative covers and advertisements. The collection has never been included in the library’s catalogue, and its exact contents are therefore unknown."
