An encyclopedia (alternatively encyclop√¶dia) is a written compendium of knowledge. The term comes from the Greek words εγκύκλιος παιδεία, enkyklios paideia ("in a circle of instruction"). This comes from εγκύκλιος, "circuit-shaped," from κύκλος ("circuit") and παιδεία, ("instruction"). Many encyclopedias are titled Cyclopaedia and the terms are interchangeable.

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 Encyclopedia Judaica.

Many dictionaries are encyclopedic in their range, especially those concerned with a particular field (such as the Dictionary of National Biography, the Dictionary of American Naval Fighting Ships, and Black's Law Dictionary). Encyclopedic works have been produced throughout much of human history, but the term encyclopedia was not used to refer to such works until the 16th century.

There are two main methods of organizing encyclopedias: the alphabetical method (consisting of a number of separate articles, organised in alphabetical order), or organization by hierarchical categories. The former is the most common by far, especially for general works.

Early encyclopedic works

The idea of collecting all of the world's knowledge within arm'Library_of_Alexandria" title ="Library of Alexandria">Library of Alexandria and Pergamon. Many writers of antiquity (such as Aristotle) attempted to write comprehensively about all human knowledge.

The Chinese emperor Cheng-Zu of the Ming Dynasty oversaw the compilation of the Yongle Encyclopedia, one of the largest encyclopedias in history, which was completed in 1408 and comprised over 11,000 handwritten volumes, of which only about 400 now survive.

In the succeeding dynasty, the Chinese emperor Qianlong of the Qing Dynasty personally composed 40,000 poems as part of a 4.7 million page library in 4 divisions, including thousands of essays. It is instructive to compare his title for this knowledge, Watching the waves in a Sacred Sea to a Western-style title for all knowledge.

The early Muslim compilations of knowledge in the middle ages included many comprehensive works, and much development of what we now call scientific method, historical method, and citation. Notable works include Abu Bakr al-Razi'Mutazilite" title ="Mutazilite">Mutazilite Al-Kindi'Ibn_Sina" title ="Ibn Sina">Ibn Sina'Asharite" title ="Asharite">Asharites, al-Tabri, al-Masudi, Ibn Rustah, al-Athir, and Ibn Khaldun, whose Muqadimmah contains cautions regarding trust in written records that remain wholly applicable today. These people had an incalculable influence on methods of research and editing, due in part to the Islamic practice of isnad which emphasized fidelity to written record, checking sources, and skeptical inquiry.

However, these works were rarely available to more than specialists: they were expensive, and written for those extending knowledge rather than (with some exceptions in medicine) using it.

Modern encyclopedias

The modern idea of the general purpose widely distributed printed encyclopedia goes back to just a little before Denis Diderot and the 18th century encyclopedists.

Although John Harris is often credited with establishing the now-familiar encyclopedia format in 1704 with his Lexicon technicum, the English physician and philosopher Sir Thomas Browne specifically employed the word encyclopaedia in the preface to his readers to describe his work Pseudodoxia Epidemica or Vulgar Errors as early as 1646. Browne structured his encyclopaedia upon the time-honoured schemata of the Renaissance, the so-called 'scale of creation' which ascends a hierarchical ladder via the mineral, vegetable, animal, human, planetary and cosmological worlds. Browne's compendium of refutations of common errors of his age was England'Pseudodoxia_Epidemica" title ="Pseudodoxia Epidemica">Pseudodoxia Epidemica also found itself upon the bookshelves of many educated European readers for throughout the late seventeenth and early eighteenth centuries it was translated into the French, Dutch and German languages as well as Latin.

Ephraim Chambers published his Cyclopaedia in 1723. The French translation of this was the inspiration of the Encyclopedie.

The venerable Encyclopædia Britannica had a modest beginning in Scotland: from 1768 to 1797 three editions were published. Perhaps the most famous early encyclopedia was the French Encyclopédie, edited by Jean Baptiste le Rond d'Alembert and Denis Diderot and completed in 1772 - 28 volumes, 71,818 articles, 2,885 illustrations.

The early years of the nineteenth century saw a flowering of encyclopedia publishing in Britain, Europe and America. In England Rees's Cyclopaedia (1802-1819) contains an enormous amount in information about the industrial and scientific revolutions of the time. A feature of these publications is the high-quality illustrations made by engravers like Wilson Lowry of art work supplied by specialist draftsmen like John Farey, Jr. Encyclopaedias were published in Scotland, as a result of the Scottish Enlightenment, for education there was of a higher standard than in the rest of Britain.

Encyclopædia Britannica appeared in various editions throughout the century, and the growth of popular education and the Mechanics Institutes, spearheaded by the Society for the Diffusion of Useful Knowledge led to the production of the Penny Cyclopaedia, as its title suggests issued in weekly numbers at a penny each like a newspaper.

In the 20th century, Encyclopædia Britannica reached its sixteenth edition, and cheap encyclopedias such as Harmsworth's Encyclopaedia, and Everyman's Encyclopaedia were common.

More recently encyclopedias are also being published online.

Traditional encyclopedias are written by a number of employed text writers, usually people with an academic degree. This is not the case with Wikipedia, a project started in 2001 with the goal to create a free encyclopedia. Anyone can add or improve text, images and sounds. The contents are licensed under a free copyleft license (the GFDL). By 2004 the project has managed to produce over a million articles in over 80 languages.

Encyclopedias are essentially derivative from what has gone before, and particularly in the 19th century piracy was common. To make space for modern topics, valuable material of historic use has to be discarded. But old encyclopedias should not be overlooked, especially for a record of changes in science and technology.

Encyclopedia making

The encyclopedia'Disk" title ="Disk">disk-based or on-line computer format, and all major printed encyclopedias had moved to this method of delivery by the end of the 20th century. Disk-based (typically CD-ROM format) publications have the advantage of being cheaply produced and extremely portable. Additionally, they can include media which is impossible in the printed format, such as animations, audio, and video. Hyperlinking between conceptually related items is also a significant benefit. On-line encyclopedias offer the additional advantage of being (potentially) dynamic: new information can be presented almost immediately, rather than waiting for the next release of a static format (as with a disk or paper based publication).

Information in a printed encyclopedia necessarily needs some form of hierarchical structure, and traditionally the method employed is to present the information ordered alphabetically by the article title. However with the advent of dynamic electronic formats the need to impose a pre-determined structure is unnecessary. Nonetheless, most electronic encyclopedias still offer a range of organisational strategies for the articles, such as by subject area or alphabetically.

Note on spelling

Encyclopedia is the dominant spelling used in the United States; an alternate spelling, encyclopædia (sometimes rendered encyclopaedia, without the æ ligature) is commonly used in British and Commonwealth English. The digraph ae or æ, the normal Latin rendering of the Greek diphthong ai, is usually changed to e in American orthography, for example in other words from the root paid- such as pædiatrician (American pediatrician). Contemporary British usage often makes the same simplification; in this case, though, the Oxford English Dictionary asserts that the spelling with æ "has been preserved from becoming obsolete by the fact that many of the works so called have Latin titles, as Encyclopædia Britannica", which use the spelling with æ in their names.

Both the British Oxford English Dictionary and the U.S. Webster's Third New International Dictionary permit both spellings, although the OED prefers the æ form, and Webster's prefers the e form. The citations given in the OED are roughly evenly divided between the two spellings.
