This document summarizes Maynooth University Library's open publishing initiatives. The library supports open publishing to address local needs, promote open access, and give authors more control over disseminating their work. It hosts three open access journals - the Journal of Mediation and Applied Conflict Analysis, The Open Journal of Astrophysics, and the Journal of Military History and Defence Studies - on its institutional repository and open journal platforms. The library also took over hosting of Dancecult, a journal on electronic dance music culture. Future plans include collaborating with more faculty interested in open access publishing and expanding the library's open publishing activities.
