This is a collection of pioneering articles on the topics of probabilistic expert systems and the Dempster-Shafer theory. It includes articles on the meaning of probability, on the propagation of evidence, on qualitative and fuzzy alternatives to probabilities and degrees of belief, and on the problem of integrating probability with logic.

When the collection was published in 1990, it served as an excellent background and introduction to the emerging field of "uncertainty in artificial intelligence." With the subsequent expansion of the field (see http://www.auai.org/), the collection is no longer adequate as an introduction, and so it has been allowed to go out of print. However, younger readers may find its table of contents and chapter introductions still useful for their pointers to various antecedents and roots. So I reproduce some of these below.
