Encyclopdia Britannica was published in the United States of America.
 In its first years, the Britannica's main competitor was the general encyclopaedia of Ephraim Chambers and, soon thereafter, Rees's Cyclopdia and Coleridge's Encyclopdia Metropolitana
 Nevertheless, from the 9th edition onwards, the Britannica was widely considered to have the greatest authority of any general English-language encyclopaedia, especially because of its broad coverage and eminent authors
