We are the Britannica Group, worldwide leaders in education, knowledge, and information for more than 250 years. Under our Encyclopædia Britannica and Merriam-Webster imprimaturs, we provide people all over the world — students, teachers, researchers, and casual learners — with reliable, lively, and relevant school curricula, and trustworthy information on subjects ranging from language and science, history and the arts, and much more.

We regard learning as one of life’s most valuable pursuits and one of its greatest pleasures. “It makes my brain feel good,” one of our young friends once told us, and we couldn’t agree more.

Whatever you want to know, for whatever reason you want to know it, and by whatever means you want to learn it, we’re here to help. Please see for yourself.

The Encyclopædia Britannica Eleventh Edition (1910–1911) is perhaps the most famous edition of the Encyclopædia Britannica. Some of its articles were written by the best-known scholars of the day. The articles are still of value and interest to modern scholars as cultural artifacts of the 19th and early 20th centuries. ( )
