Long Term Needs

To ensure that the map catalog remains an up-to-date, viable resource, we all need to do the following:

  • enter all newly-published maps into the map catalog,

  • when a map goes out of print, update its map catalog record,

  • when a map product or its metadata is placed online, update its map record,

  • notify the USGS staff when there is a change in personnel working on the map catalog.

Please keep these needs in mind, and contact us if you have any questions or comments. And, thanks for agreeing to work with us on this project!
