UX in Libraries (UXLibs) is a global community of practice committed to exploring, sharing and advocating for UX research and design methods in library and learning services in the academic and public sectors. 2018 saw our fourth annual international conference, held in Sheffield, which once again brought together delegates from all over the world and this year focused on inclusivity. This volume collects together contributions from our conference speakers including Sara Lerén, Christian Lauersen, Janine Bradbury and Kit Heyam, all of whom wowed attendees with their insights and perspectives. Fascinating workshop content, delegate papers and material presented under our research in progress banner ('UXLabs') are also collected here. If you are already applying user experience research and design or are just dipping your toe in the water, and want to find out what all the fuss is about, this second UXLibs Yearbook is the resource for you. This volume is edited by UX trainer and consultant Andy Priestner, who is also the Chair and creator of the UX in Libraries conference.
