Encyclopedias have existed for around 2,000 years and have evolved considerably during that time as regards language (written in a major international or a vernacular language), size (few or many volumes), intent (presentation of a global or a limited range of knowledge), cultural perspective (authoritative, ideological, didactic, utilitarian), authorship (qualifications, style), readership (education level, background, interests, capabilities), and the technologies available for their production and distribution (hand-written manuscripts, small or large print runs, Internet). As a valued source of reliable information compiled by experts, printed versions found a prominent place in libraries, schools and other educational institutions.

digital and open-source versions in the 21st century, such as

Characteristics
The modern encyclopedia was developed from the
dictionary in the 18th century. Historically, both encyclopedias and dictionaries have been researched and written by well-educated, well-informed content
experts, but they are significantly different in structure. A dictionary is a linguistic work which primarily focuses on alphabetical listing of

the meaning, significance or limitations of a
term, and how the term relates to a broader field of knowledge.
To address those needs, an encyclopedia article is typically not limited to simple definitions, and is not limited to defining an individual word, but provides a more extensive meaning for a ''subject or
discipline''. In addition to defining and listing synonymous terms for the topic, the article is able to treat the topic's more extensive meaning in more depth and convey the most relevant accumulated knowledge on that subject. An encyclopedia article also often includes many
maps and
illustrations, as well as

Four major elements
There are four major elements that 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 every field (the English-language ''

# Works of encyclopedic scope aim to convey the important accumulated knowledge for their subject domain, such as an encyclopedia of

,
philosophy or
law. Works vary in the breadth of material and the depth of discussion, depending on the
target audience.
# Some systematic method of organization is essential to making an encyclopedia usable for reference. There have historically been two main methods of organizing printed encyclopedias: the
alphabetical method (consisting of a number of separate articles, organized in alphabetical order) and organization by
hierarchical categories.
The former method is today the more common, especially for general works. The fluidity of

Encyclopedic dictionaries
Some works entitled "dictionaries" are actually similar to encyclopedias, especially those concerned with a particular field (such as the ''
Dictionary of the Middle Ages

Macquarie Dictionary,'' Australia's national dictionary, became an

Differences between encyclopedias and dictionaries
There are some broad differences between encyclopedias and dictionaries. Most noticeably, encyclopedia articles are longer, fuller and more thorough than entries in most general-purpose dictionaries.
There are differences in content as well. Generally speaking, dictionaries provide
linguistic information about words themselves, while encyclopedias focus more on the thing for which those words stand.
Thus, while dictionary entries are inextricably fixed to the word described, encyclopedia articles can be given a different entry name. As such, dictionary entries are not fully translatable into other languages, but encyclopedia articles can be.
In practice, however, the distinction is not concrete, as there is no clear-cut difference between factual, "encyclopedic" information and linguistic information such as appears in dictionaries.
Thus encyclopedias may contain material that is also found in dictionaries, and vice versa.
In particular, dictionary entries often contain factual information about the thing named by the word.
History
Encyclopedias have progressed from the beginning of history in written form, through medieval and modern times in print, and most recently, displayed on computer and distributed via computer networks, including the Internet.
Written encyclopedias
The earliest encyclopedic work to have survived to modern times is the ''

The Spanish scholar
Isidore of Seville was the first Christian writer to try to compile a ''
summa'' of universal knowledge, the ''
Etymologiae'' (c. 600–625), also known by classicists as the ''Origines'' (abbreviated ''Orig''.). This encyclopedia—the first such Christian
epitome—formed a huge compilation of 448 chapters in 20 volumes
[MacFarlane 1980:4; MacFarlane translates ''Etymologiae'' viii.] based on hundreds of classical sources, including ''Natural Historia''. Of Etymologiae in its time it was said ''quaecunque fere sciri debentur'', "practically everything that it is necessary to know".

), newly discovered and translated. The ''Margarita Philosophica'' by
Gregor Reisch, printed in 1503, was a complete encyclopedia explaining the
seven liberal arts.
Financial, commercial, legal, and intellectual factors changed the size of encyclopedias. Middle classes had more time to read and encyclopedias helped them to learn more. Publishers wanted to increase their output so some countries like Germany started selling books missing alphabetical sections, to publish faster. Also, publishers could not afford all the resources by themselves, so multiple publishers would come together with their resources to create better encyclopedias. Later, rivalry grew, causing copyright to occur due to weak underdeveloped laws.
John Harris is often credited with introducing the now-familiar alphabetic format in 1704 with his English ''Lexicon Technicum: Or, A Universal English Dictionary of Arts and Sciences: Explaining not only the Terms of Art, but the Arts Themselves'' – to give its full title. Organized alphabetically, its content does indeed contain explanation not merely of the terms used in the arts and sciences, but of the arts and sciences themselves.

'', had a modest beginning in Scotland: the first edition, issued between 1768 and 1771, had just three hastily completed volumes – A–B, C–L, and M–Z – with a total of 2,391 pages. By 1797, when the third edition was completed, it had been expanded to 18 volumes addressing a full range of topics, with articles contributed by a range of authorities on their subjects.
The ''Encyclopædia Britannica'' appeared in various editions throughout the nineteenth 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 early 20th century, the ''Encyclopædia Britannica'' reached its eleventh edition, and inexpensive encyclopedias such as ''
Harmsworth's Universal Encyclopaedia'' and ''
Everyman's Encyclopaedia'' were common.

from 1796 to 1808, in 6 volumes. Paralleling other 18th century encyclopedias, its scope was expanded beyond that of earlier publications, in an effort at comprehensiveness. It was, however, intended not for scholarly use but to provide results of research and discovery in a simple and popular form without extensive detail. This format, a contrast to the ''Encyclopædia Britannica'', was widely imitated by later 19th century encyclopedias in Britain, the United States, France, Spain, Italy and other countries. Of the influential late-18th century and early-19th century encyclopedias, the ''Conversations-Lexikon'' is perhaps most similar in form to today's encyclopedias.
E.s in the US
In the United States, the 1950s and 1960s saw the introduction of several large popular encyclopedias, often sold on installment plans. The best known of these were ''
World Book'' and ''
Funk and Wagnalls''. As many as 90% were sold
door to door.
Jack Lynch says in his book ''You Could Look It Up'' that encyclopedia salespeople were so common that they became the butt of jokes. He describes their sales pitch saying, "They were selling not books but a lifestyle, a future, a promise of social mobility." A 1961 ''World Book'' ad said, "You are holding your family's future in your hands right now," while showing a feminine hand holding an order form.

The Hitchhiker's Guide to the Galaxy'', a fictional encyclopedia used in the works of
Douglas Adams. It became known as Project Galactic Guide.
