Janitors of knowledge: constructing knowledge in the everyday life of Wikipedia editors

Purpose The aim of this article is to explore how trustworthy knowledge claims in Wikipedia are constructed by focusing on the everyday practices of Wikipedia editors. The article focuses particularly on the role of references to external sources for the stabilisation of knowledge in Wikipedia. Design/methodology/approach The study is inspired by online ethnography. It includes eleven Wikipedia editors, together with the sociotechnical resources in Wikipedia. The material was collected through interviews, online observations, web documents and discussions, and e-mail questions. The analysis was carried out from a perspective of science and technology studies (STS). Findings Wikipedia can be regarded as a laboratory for knowledge construction in which the already published is being recycled. The references to external sources anchor the participatory encyclopaedia in the ecology of established media and attribute trust to the knowledge published. The policy on Verifiability is analysed as an obligatory passage point to which all actors have to adjust. Active Wikipedia editors can be seen as akin to janitors of knowledge, as they are the ones who, through their hands-on activities, keep Wikipedia stable. Originality/value The study develops an innovative understanding of the knowledge construction culture in one of the most popular sources for information on the internet. By highlighting the ways in which trust is established in Wikipedia, a more reflexive use of the participatory encyclopaedia is made possible. This is of value for information literacy training.
