THE MOST IMPORTANT 18TH CENTURY ATLAS FOR AMERICA: a "geographical description of the whole continent of America, as portrayed in the best available maps in the latter half of the eighteenth century ... as a major cartographic reference work it was, very likely, consulted by American, English, and French civilian administrators and military officers during the Revolution" (Ristow).The American Atlas has several editions dated 1776. This copy with the second title-page mentioning 49 plates and with Holland's name listed as major, and the letterpress index listing 30 maps (the first index lists 29 maps). There are various combinations of maps included in the several 1776 editions which were made up. Each map has an ink-numbered stamp on the upper righthand verso. Bowen & Gibson's "An Accurate Map of North America," numbered 5-6, is an earlier issue, with imprint dated July 2, 1775 (Stevens & Tree 49d). Map 8, British North America, was originally dated 1775 and was revised here to Aug. 17, 1776. The New York and New Jersey map (map 17) was likewise originally dated 1775 and now revised to Aug. 17, 1776 (when its number was changed from 18 to 17 ). The map of Lake Champlain was not included in the 1775 edition, but is present here as number 18 in its first state. Scull's map of Pennsylvania was previously numbered 17, but is here number 20. The present edition includes A new Map of the Province of Quebec (a significant addition) in place of Jefferys' map of the Middle British Colonies.
