==Cataloging==
Unusually for a public library, the Minneapolis Public Library used the [[Library of Congress Classification]]. Prior to 1969 it used the [[Dewey Decimal Classification|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.<ref>Andy Sturdevant.
