Auction of items from the Geological Society of FranceThe Geological Society of France (La Société géologique de France, SGF), located in the heart of Paris, is one of the world's oldest societies. It was founded in 1830 by geologist Ami Boué, who published the first geological map of the world, and mineralogist Alexandre Brongniart. Since the early 19th century—a period that saw the rise of many new scientific fields, especially the natural sciences—the SGF has steadily exchanged ideas with geologists and learned societies worldwide.
Its library, one of the richest in the world, holds over 100,000 maps and works, some dating back to the 16th century. Geology underpins most developed societies’ activities, which depend on energy sources, raw materials, and water, and require a better understanding of the planet to anticipate new opportunities and natural or human-caused risks.
The mission of the SGF is to highlight the achievements of all French geologists—teachers, researchers, or industrialists—and to place current geological science in historical and societal context.
SGF aims to make its collection more accessible and share its knowledge with researchers and the public by:
- digitizing most of its collection
- transitioning its paper journal Terre & Sciences to full digital publication
- making its website the leading geoscience portal, including the first electronic directory of all geoscientists in France.
Achieving these goals and building a professional web portal requires significant costs.
To directly fund digitization and improve digital access, the SGF has decided to auction several of its items, which will serve as a critical source of funding.
