MapHist Forum is a forum whose primary focus is historical maps, atlases, globes and other cartographic documents. The forum is open to all persons interested in the history of cartography and discussion is encouraged on all aspects of this broad subject.
The primary purpose of MapHist is to encourage individuals to communicate current research; evaluate methods and tools of analysis; announce important acquisitions and news; announce position vacancies; announce new publications; investigate library holdings; and to share information between conferences and the appearance of relevant journals.
The MapHist forum is the continuation of the MapHist e-mail discussion list, which was active from 1994 to January 2012.
