What are handbooks?
Often times a particular topic gains ongoing scholarly interest that attracts the interest of a publisher or research organization. Authors who are known in the particular field of study are often asked to contribute chapters or to provide editorial oversight for these types of publications. Handbooks can provide a useful overview of the topic and help you identify some of the "movers and shakers" in that particular area of research.
