Encyclopedia Britannica

 

The entire text of Encyclopedia Britannica. It includes news, commentary and features on contemporary issues of the day, selected by Britannica editors from a wide range of respected publishers. These are combined and displayed in context with the encyclopedia s content, along with a full line of general information and community services such as e-mail, weather forecasts and financial market reports. Britannica.com is aimed principally at US consumers and will be followed by the launch in 2000 of the UK site which will be tailored to British and European markets. The move is a dramatic new direction for Britannica, which has sold millions of copies of its encyclopedia throughout the world since its first edition in 1768.
