This dictionary in its concept and content is an integrated whole though out of necessity it impinges on associated disciplines and inevitably makes use of a wide range of similar terminology. In compiling this dictionary, the main criterion for inclusion has been usage. Geographical textbooks and periodicals have been thoroughly examined. It includes all those terms used in a specific geographical context or in a specialist sense which differs from General practice or popular usage. Foreign words are enumerated where they have been accepted in English geographical literature, especially where no satisfactory translation exists. The emphasis throughout is on specific factual information, rather than on bare definition and can be conveniently accessed alphabetically.
