Early published accounts by explorers make up another significant category of the Library's holdings. These include A Voyage to the Pacific Ocean (1784), the first printed account of Captain James Cook's expedition undertaken from 1776 to 1780. Published in four volumes, this work contains numerous charts and maps. Captain Cook's Three Voyages to the Pacific Ocean (1797) is abridged from the quarto editions and includes a biography of Cook. A 1955 edition of The Journals of Captain James Cook is a reproduction from the original manuscript containing 58 plates in portfolio. A Voyage of Discovery to the North Pacific, and Round the World, a six-volume set by George Vancouver (1801), recounts his exploration of the North Pacific from 1790 to 1795.
