Maynooth University (MU) Library has developed an organizational culture that promotes professional development for all Library staff. This has led to significant Library-oriented publishing and presenting at conferences nationally and internationally. Focusing on the publishing aspect, this article contextualizes professional development – which is core to publishing and presenting – at MU Library. After a brief literature review, it explores how library practice can be the basis of professional and peer-reviewed articles and how academic writing is a relevant form of continuing professional development (CPD) for library staff at all grades. The case study reviews publications by MU Library staff over a five-year period (2013–2018). It identifies the main types of publication, key publication outlets and the main topics covered. It concludes with a reflection on a range of issues including the benefits and challenges of sustaining a writing culture.
