This book is about Austrian philosophy leading up to the philosophy of Rudolf Haller. It emerged from a philosophy conference held at the University of Arizona by Keith Lehrer with the support of the University of Arizona and Austrian Cultural Institute. We are grateful to the University of Arizona and the Austrian Cultural Institute for their support, to Linda Radzik for her editorial assistance, to Rudolf Haller for his advice and illuminating autobiographical essay and to Ann Hickman for preparing the camera-ready typescript. The papers herein are ones preseJ,lted at the conference. The idea that motivated holding the conference was to clarify the conception of Austrian Philosophy and the role of Rudolf Haller therein. Prof Rudolf Haller of Karl-Franzens University of Graz has had a profound influence on modern philosophy, which, modest man that he is, probably amazes him. He has made fine contributions to many areas of philosophy, to aesthetics, to philosophy of language and the theOl)' of knowledge. His seven books and more than two hundred articles testify to his accomplishments. But there is something else which he did which was the reason for the conference on Austrian Philosophy in his honor. He presented us, as Barry Smith explains, with a unified conception of Austrian Philosophy.

A newly reorganized, up-to-date overview of key reference works in philosophy, reflects a veritable explosion of reference sources, both print and online, published over the past decade. Nearly 300 of the 700+ entries consist of new material, with an additional 50 entries substantially revised and updated. English-language sources are emphasized, but important non-English works are also well represented. For professional philosophers, philosophy educators, students from beginning to graduate, and librarians. This guide represents a substantial updating and complete re-organization of the author's 1997 Philosophy: A Guide to the Reference Literature, 2nd edition (1st edition, 1986). It reflects a veritable explosion of reference sources, both print and online, in the field of philosophy over the past decade. Nearly 300 entries (or 40 percent) are entirely new. An additional 50 or so entries have substantial revisions recording new editions, changes in serial publications, series, and websites, or additional volumes completed in multi-volume sets. In addition, it has been entirely re-organized along topical lines. Each of its twenty-three chapters is divided into four sections: (1) general sources, (2) history of philosophy, (3) branches of philosophy, and (4) miscellanea. This new arrangement accords better with the greatly expanded range of philosophy reference sources and makes it easier for the user to identify related sources of different types (bibliographies, dictionaries, web gateways, etc.) on the same topic. Like its predecessor Guide to Reference Sources in Philosophy, the 3rd edition aims to serve a diverse audience of professional philosophers, philosophy educators, students from beginning to graduate, and librarians. All entries include generous annotations that are often evaluative as well as descriptive. English-language sources are emphasized, but non-English works important to researchers or of interest to users with facility in other languages are also well-represented.
