This multi-authored collection covers the methodology and philosophy of collective writing. It is based on a series of articles written by the authors in Educational Philosophy and Theory, Open Review of Educational Research and Knowledge Cultures to explore the concept of collective writing. This tenth volume in the Editor's Choice series provides insights into the philosophy of academic writing and peer review, peer production, collective intelligence, knowledge socialism, openness, open science and intellectual commons. This collection represents the development of the philosophy, methodology and philosophy of collective writing developed in the last few years by members of the Editors' Collective (EC), who also edit, review and contribute to Educational Philosophy and Theory (EPAT), as well as to PESA Agora, edited by Tina Besley, and Access, edited by Nina Hood, two PESA 'journals' recently developed by EC members. This book develops the philosophy, methodology and pedagogy of collective writing as a new mode of academic writing as an alternative to the normal academic article. The philosophy of collective writing draws on a new mode of academic publishing that emphasises the metaphysics of peer production and open review along with the main characteristics of openness, collaboration, co-creation and co-social innovation, peer review and collegiality that have become a praxis for the self-reflection emphasising the subjectivity of writing, sometimes called self-writing. This collection, under the EPAT series Editor's Choice, draws on a group of members of the Editors' Collective, who constitute a network of editors, reviewers and authors who established the organisation to further the aims of innovation in academic writing and publishing. It provides discussion and examples of the philosophy, methodology and pedagogy of collective writing. Split into three sections: Introduction, Openness and Projects, this volume offers an introduction to the philosophy and methodology of collective writing. It will be of interest to scholars in philosophy of education and those interested in the process of collective writing.
