Over 9,000 books "mislaid" at British Library

Every librarian understands the concept of "missing" books: those volumes stolen, mis-shelved, or misplaced that usually turn up. But if those books are at the British Library and number in the thousands, the problem could be disastrous.

According to officials at the library, over 9,000 books are missing including a medieval text on astronomy and a "Renaissance treatise on theology and alchemy." Librarians believe the books have been mislaid rather than stolen.
