This is a list of all editions and translations of Ptolemy's Geographia held in the Library of Congress. In the description of each edition, we have specified the place and date of publication, language, and some names of contributors. The following titles link to fuller bibliographic information in the Library of Congress Online Catalog. Links to additional online content are included when available.

Copies are held in the collections of two reading rooms, the Geography & Map Reading Room and the Rare Book/Special Collections Reading Room. For many editions, both locations hold at least one copy, but others are held only in one reading room. The holding location(s) is specified in the description of each edition, and information on the location of specific copies can be found in the catalog record under "Item Availability." See each reading room's website for access policies; items in the Geography & Map Reading Room are held in the rare materials Vault.

In addition to these atlases, many individual maps from various editions of Ptolemy's Geographia can be found in the Geography and Map Division single map collection. Many have been individually cataloged, and many others are described in collection-level records. The Division also holds numerous facsimiles of both Ptolemaic atlases and individual maps.
