This report and dataset analyses the research outputs, and monographs in particular, from the Research Excellence Framework 2014 (REF2014) as part of the AHRC-funded research project titled: The Academic Book of the Future (https://academicbookfuture.org/). The REF2014 submission information delivered to HEFCE provides a rich data set that can provide a means of finding out more about the academic books submitted in the last REF cycle (2008-2013). The analysis of the data provides useful indicator data about academic book writing and publishing, and will further augment the analysis already provided by HEFCE. The research focuses upon the Main Panel D for Arts and Humanities. Within this Panel, data can be investigated by Unit of Assessment Subject Area and by Research Output Type. The HEFCE data was mined for ISBN data which was compared against bibliographic catalogues held at The British Library to provide additional supporting data.
