Wikipedia @ 20 is a book of essays about Wikipedia published by the MIT Press in late 2020, marking 20 years since the creation of Wikipedia. It was edited by academic and author Joseph M. Reagle Jr. and social researcher Jackie Koerner. Contributions came from 34 other Wikipedians, Wikimedians, academics, researchers, journalists, librarians, artists and others, reflecting on particular histories and future themes in Wikipedia discussions.[1][2]
Background
The title "Wikipedia @ 20" has a distinct style used in 2021 around celebration of Wikipedia's birthday, and the subtitle paraphrases the closing remarks of the preface:
"Though Wikipedia was revolutionary twenty years ago, it has yet to become the revolution we need. The important work of sharing knowledge, connecting people, and bridging cultures continues."
The book features an introduction by the editors and 21 essays split into three sections: Hindsight, Connection, and Vision. Essays were selected through an open submission process in the spirit of Wikipedia and published using open publishing platform PubPub.[2]
