The long awaited report on the Copyright Office's investigation into the problem with orphan works - copyrighted works whose owners may be impossible to identify and locate - is now available at http://www.copyright.gov/orphan/. The Report is available in two versions, the Full Report with Appendices, and the Main Text (no appendices).
I can't wait to see what they have recommended - and how many of Mary's good ideas made it into the final version.
