This paper describes Community Proofreading as implemented by Language Science Press via PaperHive. Community members comment on a final draft version of a book and highlight possible improvements. A database of over 43.000 comments was compiled, which allows for the formulation of novel research questions. Two of those (“small details vs. big picture” and “reviewer fatigue”) are tested in this paper. Furthermore, the paper shows that Community Proofreading can serve as a tool to attract new authors.
