his ScienceBase community represents the National Digital Catalog of the National Geological and Geophysical Data Preservation Program (NGGDPP). The National Digital Catalog includes metadata records describing geological and geophysical physical samples managed by state geological agencies. These samples include rock samples, thin sections, field notebooks, photographs, maps, datasets, and many more. Samples are described using metadata elements identified by the NGGDPP as important for discovering, understanding, accessing, and using physical collections. Contact and access information is provided for each sample to enable users to access information and material. More information about the National Digital Catalog is available at: http://datapreservation.usgs.gov/
