In 732 major articles, Raymond Howgego's Encyclopedia of Exploration 1800 to 1850 attempts to detail every significant traveller, voyager or expedition that set out during the period. Its indexes provide the names of over 3000 travellers and 1000 ships, while the bibliographies cite more than 10,000 works of reference. Extensive biographical information is included for the travellers themselves, placing every expedition thoroughly in its historical context. The text is fully cross-referenced between articles, whilst every article is supplemented by a comprehensive bibliography of both primary and secondary sources.
