A dictionary is a listing of lexemes from the lexicon of one or more specific languages, often arranged alphabetically, which may include information on definitions, usage, etymologies, pronunciations, translation, etc. It is a lexicographical reference that shows inter-relationships among the data.
An encyclopedia or encyclopædia 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.
Lexicography is the study of lexicons, and is divided into two separate academic disciplines. It is the art of compiling dictionaries.
A reference work is a non-fiction work, such as a paper, book or periodical, to which one can refer for information. The information is intended to be found quickly when needed. Such works are usually referred to for particular pieces of information, rather than read beginning to end. The writing style used in these works is informative; the authors avoid use of the first person, and emphasize facts.
Slang is vocabulary of an informal register, common in verbal conversation but avoided in formal writing. It also sometimes refers to the language generally exclusive to the members of particular in-groups in order to establish group identity, exclude outsiders, or both. The word itself came about in the 18th century and has been defined in multiple ways since its conception.
Encyclopedism is an outlook that aims to include a wide range of knowledge in a single work. The term covers both encyclopedias themselves and related genres in which comprehensiveness is a notable feature. The word encyclopedia is a Latinization of the Greek enkýklios paideía, which means all-around education. The encyclopedia is "one of the few generalizing influences in a world of overspecialization. It serves to recall that knowledge has unity," according to Lewis Shore, editor of Collier's Encyclopedia. It should not be "a miscellany, but a concentration, a clarification, and a synthesis", according to British writer H. G. Wells.
Cyclopædia: or, An Universal Dictionary of Arts and Sciences is an encyclopedia prepared by Ephraim Chambers and first published in 1728; six more editions appeared between 1728 and 1751 with a Supplement in 1753. The Cyclopædia was one of the first general encyclopedias to be produced in English.
Lexicon Technicum: or, An Universal English Dictionary of Arts and Sciences: Explaining not only the Terms of Art, but the Arts Themselves was in many respects the first alphabetical encyclopedia written in English. Although the emphasis of the Lexicon Technicum was on mathematical subjects, its contents go beyond what would be called science or technology today, in conformity with the broad eighteenth century understanding of the terms "arts" and "science," and it includes entries on the humanities and fine arts, notably on law, commerce, music, and heraldry. However, the Lexicon Technicum neglects theology, antiquity, biography, and poetry.
The Brockhaus and Efron Encyclopaedic Dictionary is a comprehensive multi-volume encyclopaedia in Russian. It contains 121,240 articles, 7,800 images, and 235 maps. It was published in Imperial Russia in 1890–1907, as a joint venture of Leipzig and St Petersburg publishers. The articles were written by the prominent Russian scholars of the period, such as Dmitri Mendeleev and Vladimir Solovyov. Reprints have appeared following the dissolution of the Soviet Union.
Philosophy is the study of general and fundamental problems concerning matters such as existence, knowledge, values, reason, mind, and language. It is distinguished from other ways of addressing fundamental questions by being critical and generally systematic and by its reliance on rational argument. It involves logical analysis of language and clarification of the meaning of words and concepts.
The history of science during the Age of Enlightenment traces developments in science and technology during the Age of Reason, when Enlightenment ideas and ideals were being disseminated across Europe and North America. Generally, the period spans from the final days of the 16th and 17th-century Scientific Revolution until roughly the 19th century, after the French Revolution (1789) and the Napoleonic era (1799–1815). The scientific revolution saw the creation of the first scientific societies, the rise of Copernicanism, and the displacement of Aristotelian natural philosophy and Galen's ancient medical doctrine. By the 18th century, scientific authority began to displace religious authority, and the disciplines of alchemy and astrology lost scientific credibility.
Chinese encyclopedias comprise both Chinese-language encyclopedias and foreign-language ones about China or Chinese topics. There is a type of native Chinese reference work called leishu that is sometimes translated as "encyclopedia", but although these collections of quotations from classic texts are expansively "encyclopedic", a leishu is more accurately described as a "compendium" or "anthology". The long history of Chinese encyclopedias began with the Huanglanleishu and continues with online encyclopedias such as the Baike Encyclopedia.

Vietnamese encyclopedias are encyclopedias which are written in Vietnamese or are focused on Vietnam-related topics. In Vietnamese, encyclopedia are known as Bách khoa toàn thư, literally meaning "complete book of a hundred subjects". The first work which was considered as an encyclopedia of Vietnam is an 18th-century book Vân đài loại ngữ by Lê Quý Đôn, a Lê dynasty Confucian scholar. Since then, many encyclopedic works were published before the first modern and official encyclopedia was published in Vietnam.

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.
Encyclopaedistics or encyclopaedics as a discipline, is the academic scholarship of encyclopedias as sources of encyclopedic knowledge and cultural objects as well; in this sense, this discipline is also known as "encyclopaedia studies" and can be termed as "theoretical encyclopaediography" by analogy with theoretical lexicography. Encyclopaedistics as a practical activity also called "encyclopaedic practice" or "encyclopedism" is the process of assembling encyclopaedias available to the public for sale or for free. In this sense, it is the art or craft of writing, compiling, and editing the paper or online encyclopedias. As a practical activity, encyclopaedistics originated in the Middle Ages in connection with the development of compendiums based on alphabetical structuring. Encyclopaedistics is often defined as "the art and science of selecting and disseminating the information most significant to mankind".
