Purpose – This paper aims to present the results of a qualitative study of the continuing professional development (CPD) activities of academic librarians in Ireland. The benefits of CPD, the methods and strategies of engagement, and the role played by professional organisations are examined, with particular emphasis on the attitudes of librarians towards CPD. Design/methodology/approach – In total, 25 academic librarians were interviewed in depth from four universities in the greater Dublin region. A qualitative approach was chosen to allow the collection of data which was rich and informative. Findings – Academic librarians engage in CPD in multiple ways, both formal and informal, but it falls primarily to the individual librarian to find, participate in, or even create such opportunities, which raises the question of personal motivation and drive. Support from employers and professional organisations is key. Barriers to participation in CPD include time, financial restraints and lack of encouragement from employers. Research limitations/implications – The authors are cognisant of the inherent limitations in using interviews as a data collection method, including the possibility of bias. Practical implications – Academic librarians need to exploit innovative and accessible modes of CPD if they wish to navigate the changes occurring within the profession. Professional library organisations must also reinforce their support of their members in this endeavour. Incentives to participate should build on librarians' personal motivation and job satisfaction, likelihood of career progression, and deepening working relationships with non-LIS colleagues. Originality/value – To date there has been no comprehensive Irish study which has addressed the question of how academic librarians engage with the professional body of knowledge through pursuing professional development activities. This research seeks to present an Irish perspective, but also explores issues which are globally applicable within the profession.
