Baidu Baike
As of the early 2020s, the largest encyclopedias are the Chinese Baike.com (18 million articles) and Baidu Baike (16 million), followed by Wikipedias for English (6 million), German (+2 million) and French (+2 million), all of which are wholly online. More than a dozen other Wikipedias have 1 million articles or more, of variable quality and length. Measuring an encyclopedia's size by its articles is an ambiguous method since the online Chinese encyclopedias cited above allow multiple articles on the same topic, while Wikipedias accept only one single common article per topic but allow automated creation of nearly empty articles.
