This article analyzes researchers' adoption of an institutional central fund (or faculty publication fund) for open-access (OA) article-processing charges (APCs) to contribute to a wider understanding of take-up of OA journal publishing ("Gold" OA). Quantitative data, recording central fund usage at the University of Nottingham from 2006 to 2014, are analyzed alongside qualitative data from institutional documentation. The importance of the settings of U.K. national policy developments and international OA adoption trends are considered. Innovation Diffusion Theory (IDT) is used as an explanatory framework. It is shown that use of the central fund grew during the period from covering less than 1% of the University's outputs to more than 12%. Health and Life Sciences disciplines made greatest use of the fund. Although highly variable, average APC prices rose during the period, with fully OA publishers setting lower average APCs. APCs were paid largely from internal funds, but external funding became increasingly important. Key factors in adoption are identified to be increasing awareness and changing perceptions of OA, communication, disciplinary differences, and adoption mandates. The study provides a detailed longitudinal analysis of one of the earliest central funds to be established globally with a theoretically informed explanatory model to inform future work on managing central funds and developing institutional and national OA policies.

This paper reports on the extent to which higher education institutions in the UK have set up central funds and similar institutionally co‐ordinated approaches to the payment of open access article‐processing charges. It presents data demonstrating that central funds have only been set up by a minority of institutions and that the number of institutions has not changed significantly between 2009 and 2011. It then explores the barriers to the establishment of such funds and discusses recent developments that might lower these barriers. Finally, it provides a case study of the development of the central fund at the University of Nottingham in the UK and considers the sustainability of such an approach.
