The Choral Public Domain Library (CPDL) is a sheet music archive which focuses on choral and vocal music in the public domain or otherwise freely available for printing and performing (such as via permission from the copyright holder). It is a 501(c)(3), tax-deductible organization, whose contents are published under a specific copyright license, and editing articles can be allowed only for registered contributors. The site CPDL.org was launched in December 1998 by Rafael Ornes. In 2005 CPDL was ported, or converted, to wiki format, and is known as ChoralWiki. In July 2008, Ornes stepped back from the site administration and turned the operational responsibilities to a group of the site administrators. A transition committee was formed which subsequently incorporated CPDL as a non-profit under California state law and now operates CPDL. More information...
