Most people are unaware but the Copyright Office is located in the Library of Congress and the Register of Copyright is appointed by Librarian of Congress, who approves all regulations issued by the Copyright Office and oversees the budget. This arrangement stems from the deposit arrangement that publishers have with the Copyright Office and allows the Library easy access to the books. This arrangement worked during the 19th Century but is out of step with the scope of the Copyright Office and the complexity of copyright law.
To remedy the situation, the House of Representatives voted in favor of H.R.1695 in April which will make the Register of Copyrights a Presidential appointee, confirmed by the Senate, and creating a panel of Congressional leaders who would recommend at least three qualified candidates for the President to choose from. The Senate issued a mirror bill days later, which is also expected to pass.
