Encyclopedia
From ePedia, the electronic encyclopedia
An encyclopedia (alternatively encyclopaedia or encyclopædia, with ligature) is a written compendium of knowledge. The term comes from the Classical Greek ἐγκύκλιος παιδεία (enkuklios paideia), literally "a rounded education." Some encyclopedias are titled cyclopaedia, a now somewhat archaic form of the word. For a list of notable encyclopedias in history, see list of encyclopedias.
General definition
Four major elements define an encyclopedia: its subject matter, its scope, its method of organization, and its method of production.
The encyclopedia as we recognize it today developed from the dictionary in the 18th century. A dictionary is primarily focused on words and their definition, and typically provides limited information, analysis or background for the word defined. While it may offer a definition, it may leave the reader still lacking in understanding the meaning or import of a term, and how the term relates to a broader field of knowledge.
To address those needs, an encyclopedia seeks to discuss each subject in more depth and convey the most relevant accumulated knowledge on that subject, given the overall length of the particular work. An encyclopedia also often includes many maps and illustrations, as well as bibliography and statistics.
Some works titled "dictionaries" are actually more similar to encyclopedias, especially those concerned with a particular field (such as the Dictionary of the Middle Ages, the Dictionary of American Naval Fighting Ships, and Black's Law Dictionary). The Macquarie Dictionary, Australia's national dictionary, became an encyclopedic dictionary after its first edition in recognition of the use of proper nouns in common communication, and the words derived from such proper nouns.

Four major elements define an encyclopedia: its subject matter, its scope, its method of organization, and its method of production.
- Encyclopedias can be general, containing articles on topics in many different fields (the English-language Encyclopædia Britannica and German Brockhaus are well-known examples), or they can specialize in a particular field (such as an encyclopedia of medicine, philosophy, or law). There are also encyclopedias that cover a wide variety of topics from a particular cultural, ethnic, or national perspective, such as the Great Soviet Encyclopedia or Encyclopaedia Judaica.
- Works of encyclopedic scope aim to convey the important accumulated knowledge for their subject domain. Such works have been envisioned and attempted throughout much of human history, but the term encyclopedia was first used to refer to such works in the 16th century. The first general encyclopedias that succeeded in being both authoritative as well as encyclopedic in scope appeared in the 18th century. Every encyclopedic work is, of course, an abridged version of all knowledge, and works vary in the breadth of material and the depth of discussion. The target audience may influence the scope; a children's encyclopedia will be narrower than one for adults.
- Some systematic method of organization is essential to making an encyclopedia usable as a work of reference. There have historically been two main methods of organizing printed encyclopedias: the alphabetical method (consisting of a number of separate articles, organised in alphabetical order), or organization by hierarchical categories. The former method is today the most common by far, especially for general works. The fluidity of electronic media, however, allows new possibilities for multiple methods of organization of the same content. Further, electronic media offer previously unimaginable capabilities for search, indexing and cross reference. The epigraph from Horace on the title page of the 18th-century Encyclopédie suggests the importance of the structure of an encyclopedia: "What grace may be added to commonplace matters by the power of order and connection."
- As modern multimedia and the information age has evolved, they have had an ever-increasing effect on the collection, verification, summation, and presention of information of all kinds. Projects such as h2g2 and Wikipedia are examples of new forms of the encyclopedia as information retrieval becomes more simple.
