This document discusses social science approaches to e-research and categorizes them into four main categories based on their degree of pragmatic engagement and research orientation. It provides examples of projects that fall into each category, such as usability studies, agenda-neutral infrastructure development efforts, and critical analyses of e-research discourses and policies. The document also discusses potential impacts and synergies between different social science approaches and concludes that e-research projects can make previously implicit research processes more visible.
