Ohio libraries electronically through a
computer network and database in order
to streamline operations, control
costs, and increase efficiency in library
management.

was to bring libraries together to
cooperatively keep track of the world’s
information in order to best serve
researchers and scholars.

cataloging through OCLC was the
Alden Library at Ohio University on
