Online Catalog Partially Unavailable
Due to a server migration to meet security requirements, the Library’s Online Catalog will be limited to searching only, starting 5:00 p.m. EDT, August 27th. Requesting materials, and all account management activities including renewals, will be unavailable. The system is expected to be fully available again by noon EDT on August 30th. We apologize for any inconvenience this may cause you. If you have an immediate need, contact the USGS Library staff at firstname.lastname@example.org for assistance.
