Encyclopædia Britannica
From Simple English Wikipedia, the free encyclopedia
The Encyclopædia Britannica is a very big, famous encyclopaedia. It was originally only published on paper, but recently it has expanded to have digital versions as well.
Many people consider it to be the best encyclopedia, because it is accurate and has lots of detail, so any other encyclopedia can be compared against it.
