GEOREF

For the World Geographic Reference System coordinate system, see Georef. The GeoRef database is a bibliographic database of scientific literature in the geosciences, including the geology of North America and the world. Coverage ranges from 1785 to the present for North American literature, and 1933 to the present for the rest of the world. It currently contains more than 2.8 million references. It is widely considered one of the preeminent literature databases for those studying the earth sciences.

For the bibliographic database about the geosciences, see GeoRef. Georef (World Geographic Reference System) is a grid-based method of specifying locations on the surface of the Earth. Georef is essentially based on the geographic system of  latitude and longitude, but using a simpler and more flexible notation. Georef was used primarily for air navigation, particularly in military or inter-service applications, but it is rarely seen today. However, Georef can be used with any map or chart that has latitude and longitude printed on it.
