World Caf e, sometimes termed Knowledge Caf e, is now an established method of facilitating productive dialogue between a group or groups of people around an issue that matters to the group as a whole. Now a world movement, the methodology is straightforward and uses conversation as a key process to connect people, who may be from different organizations, age groups, cultures, continents, and so forth. Caf e conversations draw on the wisdom and creativity of the participants to explore issues of concern to them and to confront real life challenges. Following some background information and a brief review of the literature relating to the World Caf e, this article presents a case study of the application of the model to facilitate discussion and learning around a topic of common concern, frontline desk services, for 61 staff from 11 Irish academic libraries at Maynooth University (MU) Library in October 2015. This was part of a one-day staff development event: MU Library Innovation Day. The application of the World Caf e methodology is described. The results of the evaluation of the event are presented and discussed. Actions and outcomes are provided. Limitations of the case study are presented.
