All atlases are catalogued and filed like books within the GSG Centre. Atlases can be searched by author, title, subject heading or keyword in the library catalogue. Useful subject headings for finding atlases are:
|Atlases||For general world atlases.|
|[place name--Maps]||For national and regional atlases.|
|[place-name]--[subject]--Maps||For thematic atlases.|
The library holds most major world atlases and attempts to acquire most national atlases. Thematic and regional atlases are collected on a more selective basis. Some are also available in electronic format.
