GeoRef

The GeoRef database is a <a href="/facts/Bibliographic_database/j4417rG4">bibliographic database</a> that indexes scientific literature in the <a href="/facts/Geoscience/rQsXCSbM">geosciences</a>, including <a href="/facts/Geology/WGvVRIYF">geology</a>. Coverage ranges from 1666 to the present for North American literature, and 1933 to the present for the rest of the world. It currently contains more than 4.3 million references. It is widely considered one of the preeminent literature databases for those studying the earth sciences.
It is produced by the <a href="/facts/American_Geosciences_Institute/yTVsKPQY">American Geosciences Institute</a>, which was known as the American Geological Institute until October 2011.
"To maintain the database, GeoRef editor/indexers regularly scan more than 3,500 journals in 40 languages as well as new books, maps, and reports. They record the bibliographic data for each document and assign index terms to describe it. Each month between 6,000 and 9,000 new references are added to the database."
