The Research Ethics Library is an online resource for research ethics education. This web-based collection offers more than 80 articles written by experts on all subject areas. The library is unique in terms of its broad approach to research ethics. Our aim is for the library to serve as a resource for academic institutions by providing an introduction to the main issues in research ethics. Rather than presenting an encyclopedia or a set of answers, we aim to encourage debate and reflection. The Research Ethics Library's main target groups are academic teachers and students, but the library is used by a broader public as well.
