The Interactive Track of the Social Book Search 2014���2016 generated a lot of interaction and questionnaire data focusing on how users use professional metadata and user-generated content when searching for books, and how search interfaces can adapt to and support different stages of the search process. So far, this data has only been available to the research groups who recruited participants for the track, but many open research questions can still be addressed with these data. This paper describes the data and their possibilities and limitations. It also discusses the experience of documenting the data, in particular of documenting in line with the Manifesto on Resource Reuse in Information Interaction and Retrieval.
