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.

The English Dialect Dictionary (EDD) is the most comprehensive dictionary of English dialects ever published, compiled by the Yorkshire dialectologist Joseph Wright (1855–1930), with strong support by a team and his wife Elizabeth Mary Wright (1863–1958). The time of dialect use covered is, by and large, the Late Modern English period (1700–1903), but given Wright's historical interest, many entries contain information on etymological precursors of dialect words in centuries as far back as Old English and Middle English. Wright had hundreds of informants ("correspondents") and borrowed from thousands of written sources, mainly glossaries published by the English Dialect Society in the later 19th century, but also many literary texts written in dialect. In contrast to most of his sources, Wright pursued a scholarly linguistic method, providing full evidence of his sources and antedating modes of grammatical analysis of the 20th century. The contents of the EDD's nearly 80.000 entries were generally ignored during the 20th century but were made accessible by the interface of EDD Online, the achievement of an Innsbruck University research project first published in 2012 and repeatedly revised since.
