Eighty signed pieces of correspondence collected by Carnegie Library (Pittsburgh, Pennsylvania) librarian Sophie Levin between 1900-1911, which contain the autographs of notable figures from the late nineteenth and early twentieth centuries. The collection was originally owned by the Carnegie Library, then given to Western Michigan University management professor, Dr. Fred V. Hartenstein, who donated it to Western Michigan University Libraries in 1983.

The collection is composed of an autograph book belonging to Mary Miller (1866-1953), used from 1882 to 1907.
