An encyclopedia or encyclopaedia is a reference work or compendium providing summaries of knowledge, either general or special, to a particular field or discipline. Encyclopedias are divided into articles or entries that are arranged alphabetically by article name or by thematic categories, or else are hyperlinked and searchable. Encyclopedia entries are longer and more detailed than those in most dictionaries. Generally speaking, encyclopedia articles focus on factual information concerning the subject named in the article's title; this is unlike dictionary entries, which focus on linguistic information about words, such as their etymology, meaning, pronunciation, use, and grammatical forms.

In Japanese, encyclopedias are known as hyakka jiten (百科事典), which literally means "book of a hundred subjects," and can trace their origins to the early Heian period, in the ninth century. Encyclopedic works were published in Japan for well over a thousand years before Japan's first modern encyclopedias were published after Japan's opening to the West, during the Meiji Period (1868–1912). Several encyclopedias have been published in Japan since World War II, including several children's encyclopedias, and two major titles are currently available: the Encyclopedia Nipponica, published by Shogakukan, and the Sekai Dai-Hyakka Jiten, compiled by the Heibonsha publishing company.

The long history of Chinese encyclopedias began with the Huanglanleishu and continues with online encyclopedias such as the Baike Encyclopedia.

Early Learning House or simply the House Series is a collection of four main educational video games and two compilations for the Windows and Macintosh platforms, developed by Theatrix Interactive, Inc. and published by Edmark software. Each different game focuses on a particular major learning category with selectable skill settings for preschooler, kindergarten and elementary learners. Millie's Math House (1992) on mathematics, Bailey's Book House (1993) on language, Sammy's Science House (1994) on science, and Trudy's Time and Place House (1995) on history and geography. A spin-off, Stanley's Sticker Stories (1996), sees players create animated storybooks with the series' characters. Millie & Bailey Preschool and Millie & Bailey Kindergarten each contain the combined activities from two of the four software products. In addition the programs can be configured by an adult mode to suit students with special needs. Most of the activities in every game have two modes, one to allow learners to explore and try it out for themselves and the other for learners to follow specific tasks set by the game characters. Learners also have the option to print pictures of creative activities and record sounds in phonics activities. Later the games were re-developed by Houghton Mifflin Harcourt Learning Technology and re-published by The Learning Company with newer graphics and additional activities.
