Under the Copyright Act, the Copyright Office is responsible for advising on certain questions of copyright law. This advice manifests itself in many forms. For instance, based on advice received from the Office, the Department of Justice files briefs in federal court on behalf of the federal government on issues of copyright law. In addition, the Copyright Office issues binding opinions on questions of copyright law to the Copyright Royalty Board. The Copyright Office has now published an archive of its briefs and legal opinions, which the Office intends to keep updated.
