herbert putnam
unusually for a public library, the minneapolis public library used the library of congress classification. prior to 1969 it used the dewey decimal system, although around 1890, the library switched to the early and short-lived putnam classification system, developed by minneapolis librarian herbert putnam. he later became librarian of congress, and revised his putnam system into the current library of congress classification system.
