Encyclopedia Britannica（《大英百科全书》）used to be the king of encyclopedias. It hopes to become the most important encyclopedia again. An encyclopedia has information about many different things. It includes articles on topics like animals, science, but many people were willing to buy them. They thought Britannica was the best encyclopedia.

A few years ago, the company stopped publishing the books. It put the whole encyclopedia on the Internet. However, Britannica online is not as popular as some other online encyclopedias. About half of Britannica’s articles are free while almost all of the articles on other online encyclopedias are free.

However, Britannica began in Scotland nearly 250 years ago. It moved to Chicago in 1935. In 1990, the company sold more than 100,000 sets of books. It was Britannica’s best year. Book sales dropped after the Internet became popular. People stopped getting information only from books. They began getting it online as well. Some online encyclopedias started in the early 21st century. It was the beginning of the end of Encyclopedia Britannica books. Some online encyclopedias have millions of articles. Britannica has only 106,000. However, Britannica’s articles are more trustworthy(值得信任的). The experts make sure the articles are correct. Britannica covers most of the same general subjects as other’ online encyclopedias, but finding its articles can be more difficult. The Britannica page also has many ads. The ads help support the company.
