The caption field records some of the text that is printed on the face of the map. The North Carolina Maps project does not capture all of the text printed on the map -- doing so would be extremely time-consuming and of questionable value. The text captured in the caption field relates primarily to the creation and publication of the map itself. For example, notes about printing and engraving or about earlier versions of the map should be recorded here.
Names in the Caption Field
While the Subject - Creator field holds the Library of Congress authorized version of the name of the person or people responsible for the creation of the map, the Caption field records names as they appear on the map itself.
