The online Glossary provides access to the more than 39,000 glossary entries contained in the Fifth Edition of the print Glossary. In addition to the 13,000 updated entries that appeared in the Fifth Edition, more than 1100 changes, deletions and additions have been made to the online version since the publication of the print edition -- making the online Glossary even more up-to-date.
Users can learn the difference between look-alike pairs, such as sylvanite (a mineral) and sylvinite (a rock); the origin of terms; the meaning of abbreviations and acronyms common in the geoscience vocabulary; the dates many terms were first used; the meaning of certain prefixes; and the preferred term of two or more synonyms. Many Glossary entries contain a syllabification guide and background information.
The online Glossary is searchable using terms, words within terms or definitions, categories and Spanish-language equivalents. Boolean operators (and/or/not) are available for each search field. Search fields may also be combined or may be browsed using a pop-up word wheel.
The online Glossary includes several features not available in the print version:
Display option for images of minerals, rocks, fossils and landforms. These images are drawn from the Earth Science World Image Bank maintained by AGI.
Spanish language equivalents for many entries in the online Glossary. Translated by geoscientists whose native language is Spanish, the Spanish entries can be browsed or searched directly.
Hyperlinks to related or similar terms. Synonyms or antonyms and glossary terms appearing as parts of other term definitions are frequently hyperlinked to allow quick reference.

The Geological Surveys Database contains publications from state geological surveys and factsheets from the U.S. Geological Survey.
For more information about which state geological surveys have publications in the Geological Surveys Database, please visit the Geological Survey Websites page. Please note that the database is updated monthly with new publications.
The Geological Surveys Database includes only a subset of publications from the U.S. Geological Survey, specifically the USGS factsheet series. If you wish to search the entire set of U.S. Geological Survey publications, please visit the USGS Publications Warehouse at https://pubs.er.usgs.gov/.
Records are added to or updated in the Geological Surveys Database on a monthly basis. Metadata for new or updated records are first matched to corresponding bibliographic metadata from GeoRef and are supplemented with additional metadata from the state geological surveys if available. PDFs are processed for full-text indexing. Next the updated metadata and the full-text of the publications are loaded to the Geological Surveys Database and the corresponding records are then made available for searching.
