New Latin encyclopaedīalbor. English encyclopedia Borrowed from New Latin encyclopēdīa, encyclopaedīa (“general education”), a univerbated form of Koine Greek ἐγκύκλιος παιδείᾱ (enkúklios paideíā, “education in the circle of arts and sciences”), from Ancient Greek ἐγκύκλιος (enkúklios, “circular”) + παιδείᾱ (paideíā, “childrearing; education”) (q.v.). Nearly all modern English usage of the word was influenced by the scope and format of the French Encyclopédie by Diderot et al. (see quotation).

"The Encyclopedia which we are presenting to the public is, as its title declares, the work of a society of men of letters. Were we not of their number, we might venture to affirm that they are all favorably known or worthy of being so." — 1751, Jean-Baptiste le Rond d'Alembert, “Discours Préliminaire”, in Richard N. Schwab, Walter E. Rex., transl., Encyclopédie ou Dictionnaire raisonné des sciences, des arts et des métiers, volume 1, Paris, pages 1–45; republished as “Preliminary Discourse”, in The Encyclopedia of Diderot & d'Alembert Collaborative Translation Project (Web), Ann Arbor: Michigan Publishing, University of Michigan Library, 18 April 2009:
"The first encyclopædia written in English and with the articles alphabetically arranged was the ‘Lexicon Technicum,’ […] [in 1704], by John Harris, a London clergyman. This was a useful and popular work, though it omitted from its scope theology, biography, antiquity and poetry." — 1920, George Edwin Rines, editor, Encyclopedia Americana^(https://en.wikisource.org/wiki/The_Encyclopedia_Americana_(1920)), Volume X: Egusquiza – Falsetto, Encyclopædia:
"It would be easier to compile an encyclopedia for you than to write these longhand letters whose ink blackens the night." — 1998, “Desire”, in Billy Collins (lyrics), Tom Cipullo (music), Another Reason Why I Don't Keep a Gun in the House, performed by Matthew Morris (baritone) and Sungha Lee (pianist), Pepperdine University, Los Angeles: SongFest:
"[The Origins] can best be summarized, maybe, as an encyclopedia in the guise of an etymological dictionary, by a writer already centuries removed from some of his material." — 2018 May 20, Bill Thayer, “Isidore of Seville: The Etymologies (or Origins)”, in LacusCurtius, archived from the original on 13 Jul 2012:
"Encyclopedias were the original worldwide web. […] There was a time when you couldn't connect to the rest of the world and encyclopedias gave you that insight and they contained what people knew about everything." — 2018 July 5, Justin Zackal, quoting Jason Hilton (Assoc. Prof. of Education), “Encyclop[a]edia Britannica celebrates 250th anniversary”, in SRU News, Slippery Rock: Slippery Rock University, archived from the original on 01 Mar 2024:
