Having read dozens and dozens or books related to attachment, I can say that I wish I had found this first. This is a comprehensive summary of nearly all the major applications and research related to attachment. It exposes the reader to numerous authors and researchers in the field, and each article has its own reference list, so finding the additional sources is painless. There is a little built in redundancy on certain aspects of the history of attachment theory, which is to be expected, but some of the research is just marvelous. I found myself ordering other books by some of the contributors, because these articles are so interesting. For any dissertation or clinical reports, this is a go-to source for attachment. The index is also incredible, and whoever compiled it should be proud.
