It is not unusual for library books to be returned to the wrong library. It's also not unusual for libraries to use interlibrary loan services to return errant books to their home libraries. So when two books recently arrived at the WSU Libraries from the University of Wisconsin-Milwaukee Libraries, no one was surprised. An attached note on the books indicated that they had been anonymously returned through the UW-ML book drop. Then the staff checked the date-due slips. The first book was last circulated in 1968, and the other was last circulated in 1967. One book was titled "Essays: Moral, Political and Aesthetic." The assumption is the borrower didn't finish reading that one.
