Inside Higher Ed has an excellent article on a major fight going on in the cataloging community after the Library of Congress announced that it will no longer provide series authority records, devolving the responsibilities to individual libraries.
The LC's move has been panned by researchers, the American Library Association, and other groups. The Library of Congress has provided very little information about what prompted this decision, and was "unprepared" to discuss the issue on Thursday, according to Inside Higher Ed.
