The University of Manchester Library’s Open Access Service is well regarded across the University, has helped to achieve high levels of compliance with funder policies and has played a significant role within the institution to advocate for open access and open research more generally. Its evolving workflows reflect changes in priorities and have helped researchers to reap the benefits of making their work openly available, most notably through the Open Access+ Service. However, changes in the scholarly publishing landscape present challenges that may require more significant changes to the service.
