This e-book examines changes in the quality of user research in Library and Information Science. The diversity of methods to study users is growing and a confidence about labeling and using methods is becoming manifest. The number of research questions that a single study answers is both diminishing and at the same time growing more diverse. Research about users, their behavior and their needs were often an add-on at the end of a project. In the last two years, this situation has changed. The topic of user experience is suddenly omnipresent at conferences and in current literature. Studies about the way we do research are an important part of Library and Information Science. The papers in this e-book cover these themes.
