From the Copyright Office:
Today, the U.S. Copyright Office launched its updated website, www.copyright.gov. The website has been redesigned to be more organized, more responsive, and easier to digest.
It now features a new header with global navigation and search, and expanded width in all sections to maximize screen usage. Several individual pages have been consolidated for improved navigation. A new page, History and Education, includes a wealth of information such as the History of Copyright Law, Past Reports and Publications, and Past Announcements.
