The purpose of this paper is to quantify, review, and analyze published research output of academic librarians from 21 higher education Institutions in Ireland. A mixed approach using an online survey questionnaire, supplemented by content analysis and extensive literature scoping were used for data collection. Factors inhibiting and predicting the likelihood of research publication are identified. Motivations, barriers, and collaboration are examined. Qualitative perspectives from survey respondents are offered. The survey response was 30%. The main findings are presented and contextualized. There is evidence of moderate research growth and publication rates among the Irish LIS community; Open Access pathways are increasingly accepted. The paper has original value with both exploratory and analytical perspectives. This is the first comprehensive national study of this cohort; it adds value and a new perspective to the existing literature on academic librarians' participation in scholarly endeavours and communication.
