Micropædia
The Micropædia was introduced in 1974 with 10 books having 102,214 short articles, all of them are less than 750 words. In the 15th edition, many articles were put together, with about only 65,000 articles in 12 volumes. In general, the 750-word limit is still used and most articles are only 1-2 paragraphs; however, a few longer articles can be found in the 2007 Micropædia, such as the Internet ones, which takes up a full page.
