Motivated by the plethora of book digitization projects around the world, the Initiative for the Evaluation of XML Retrieval (INEX) launched a Book Search track in 2007. In its first year, the track focused on Information Retrieval (IR) tasks, exploring the utility of traditional and structured document retrieval techniques to books. In this paper, we propose three new tasks to be investigated at the Book Search track in 2008. The tasks aim to promote research in a wider context, across IR, Human Computer Interaction, Digital Libraries, and eBooks. We identify three novel problem areas, define tasks around these and propose possible evaluation methods.
