Usage notes[edit]

The spelling encyclopedia is standard in American English, preferred in Canadian English, accepted in Australian and International English, and also very common in British English. It is more common than encyclopaedia, for example, in UK newspapers on Google News in 2009 by a 7:3 margin.
