Welcome to Guin!

The Marilyn Potts Guin Library houses the research and teaching collection of Oregon State University's Hatfield Marine Science Center. The collection covers a broad range of marine-related topics including fisheries, aquaculture, oceanography, geology, environmental studies and biology. Particular attention is paid to collecting material on marine fisheries, marine mammals, and information specific to the Northeast Pacific Ocean. Researchers, students and staff use traditional and electronic tools to access both the local and main campus collections as well as resources throughout the world. The library staff works to help library patrons identify and retrieve resources. Involvement in regional and international consortia adds richness to the available services and resources.

Marilyn Potts Guin (1944-1989):

Marilyn was the HMSC Librarian from 1976-1989. She combined her fascination with the marine world (M.S., Oceanography, Oregon State University, 1978) with her library skills (M.L.S., University of Oklahoma, 1971) to create a unique library environment. Under her exuberant guidance, the collection grew and the library is now an integral part of the Hatfield Marine Science Center. The library was officially dedicated in her memory on July 4th, 1990.
