From the reviews:
"Dynamic Formal Epistemology contains a great deal of novel research of which I was not aware in the areas of belief change, knowledge change, modal logical approaches of such matters, and pragmatics of such matters. Overall as a collection it is admirably focussed, and it is a welcome addition to the literature in this area." Hans van Ditmarsch, University of Sevilla, Spain
“This book features a collection of twelve articles, each related in some way or another to the central theme suggested by the title: Dynamic formal epistemology. … The quality of the papers included in the book is generally good, and it contains several novel ideas and results that will no doubt be of interest to researchers working in the field. … a well-written book which is worth recommending to people working in dynamic epistemic logic and related areas.” (Sebastian Enqvist, Mathematical Reviews, Issue 2012 i)
