During the university’s earliest years in Ann Arbor, its library books were kept in one of the professors’ houses. In November 1841, it was resolved to move the library to a large room in the main university building. Among library regulations adopted then by the Board of Regents: “Borrowers of books from the Library are forbidden to write or mark in them or to turn down a leaf.”
