The HEFCE Monographs & Open Access Project was set up to identify and clarify issues around making monographs openly accessible online, taking a long-term perspective beyond REF 2020. The project examines the culture of monographs in the humanities and social sciences, whether there is a crisis for the monograph form, and how publishing innovations and access models may impact monographs. The project has convened an expert group, conducted research including focus groups, and will report findings to HEFCE in late 2014. Key issues being considered include the role and definition of the monograph, peer review and quality standards, licensing models, and ensuring a balance of private and public benefits from any new models.
