From the U.S. Copyright Office Blog:
Today, the Office is pleased to announce the launch of an online database of recent decisions (April 2016 to present) made by the Copyright Office Review Board and will update the database as new decisions are issued. The Review Board makes final determinations on second appeals regarding decisions to refuse copyright registration. Types of works that fall under the Board’s review range from music, jewelry design, computer programs, and more.
Established by regulation in 1995 the Review Board is made up of three members, including the Register of Copyrights and the Copyright Office’s general counsel, or their respective designees, and a third appointee named by the Register.
