Situated at the intersection of library and information science (LIS), Wikipedia studies, and fandom studies, this book is a digital (auto)ethnography that documents the information behavior of Wikipedia "fan editors"--that is, individuals who edit articles about pop culture media. Given Wikipedia's prominence in LIS and fan studies scholarship, both as one of the world's most heavily used reference sources and as an important archive for fan communities, fan editors are a crucial component of this ecosystem as some of Wikipedia's most active contributors. Through a combination of fieldwork observations, insight from key informants, and the author's own experiences as a Wikipedia editor, this monograph provides a rich articulation of fan editor information behavior and offers a significant contribution to scholarship in a number of fields. Scholars of library and information science, media studies, fandom studies, and popular culture will find this book of particular interest.
