Labelled deduction is an approach to providing frameworks for presenting and using different logics in a uniform and natural way by enriching the language of a logic with additional information of a semantic proof-theoretical nature. Labelled deduction systems often possess attractive properties, such as modularity in the way that families of related logics are presented, parameterised proofs of metatheoretic properties, and ease of mechanisability. It is thus not surprising that labelled deduction has been applied to problems in computer science, AI, mathematical logic, cognitive science, philosophy and computational linguistics - for example, formalizing and reasoning about dynamic state oriented' properties such as knowledge, belief, time, space, and resources.

Recent years have been blessed with an abundance of logical systems, arising from a multitude of applications. A logic can be characterised in many different ways. Traditionally, a logic is presented via the following three components: 1. an intuitive non-formal motivation, perhaps tie it in to some application area 2. a semantical interpretation 3. a proof theoretical formulation. There are several types of proof theoretical methodologies, Hilbert style, Gentzen style, goal directed style, labelled deductive system style, and so on. The tableau methodology, invented in the 1950s by Beth and Hintikka and later per fected by Smullyan and Fitting, is today one of the most popular, since it appears to bring together the proof-theoretical and the semantical approaches to the pre of a logical system and is also very intuitive. In many universities it is sentation the style first taught to students. Recently interest in tableaux has become more widespread and a community crystallised around the subject. An annual tableaux conference is being held and proceedings are published. The present volume is a Handbook a/Tableaux pre senting to the community a wide coverage of tableaux systems for a variety of logics. It is written by active members of the community and brings the reader up to frontline research. It will be of interest to any formal logician from any area."

The tableau methodology, invented in the 1950's by Beth and Hintikka and later perfected by Smullyan and Fitting, is today one of the most popular proof theoretical methodologies. Firstly because it is a very intuitive tool, and secondly because it appears to bring together the proof-theoretical and the semantical approaches to the presentation of a logical system. The increasing demand for improved tableau methods for various logics is mainly prompted by extensive applications of logic in computer science, artificial intelligence and logic programming, as well as its use as a means of conceptual analysis in mathematics, philosophy, linguistics and in the social sciences. In the last few years the renewed interest in the method of analytic tableaux has generated a plethora of new results, in classical as well as non-classical logics. On the one hand, recent advances in tableau-based theorem proving have drawn attention to tableaux as a powerful deduction method for classical first-order logic, in particular for non-clausal formulas accommodating equality. On the other hand, there is a growing need for a diversity of non-classical logics which can serve various applications, and for algorithmic presentations of these logicas in a unifying framework which can support (or suggest) a meaningful semantic interpretation. From this point of view, the methodology of analytic tableaux seems to be most suitable. Therefore, renewed research activity is being devoted to investigating tableau systems for intuitionistic, modal, temporal and many-valued logics, as well as for new families of logics, such as non-monotonic and substructural logics. The results require systematisation. This Handbook isthe first to provide such a systematisation of this expanding field. It contains several chapters on the use of tableaux methods in classical logic, but also contains extensive discussions on: the uses of the methodology in intuitionistic logics modal and temporal logics substructural logics, nonmonotonic and many-valued logics the implementation of semantic tableaux a bibliography on analytic tableaux theorem proving. The result is a solid reference work to be used by students and researchers in Computer Science, Artificial Intelligence, Mathematics, Philosophy, Cognitive Sciences, Legal Studies, Linguistics, Engineering and all the areas, whether theoretical or applied, in which the algorithmic aspects of logical deduction play a role.

"The Moving Picture World" magazine was the industry standard during the silent cinema era. This is the first index compiled for all the films reviewed in the early volumes of this journal. In 1916, the magazine itself began providing an index to film reviews. Until now, researchers and scholars had to scour page-by-page through each weekly issue from 1907-1915 to find a desired review. This new index, focusing on this period, lists films alphabetically by title, identifies manufacturers/distributors with their films, and provides full dates and page locations for reviews. The index provides easy access to reviews of theatrical films, news pictorials, series and serials, and early travelogues.

Many of the films included in this index are no longer extant; thus, contemporary reviews may be the only means for analysis of these pioneering cinematic efforts. The reviews contain valuable information about the standards and tastes of film in its infancy, and shed light on story content in those early days. Some of the titles in this index will shock the user; many will cause laughter; all are worthy of remembrance for their historical value. Over 27,000 films are listed; the preface chronicles the history of the journal and explains clearly how to use the book. No reviews are included--the index is designed to encourage and guide the user towards an increased familiarity with the "Moving Picture World," which is currently available on microfilm through the Library of Congress

One of the most significant contributors to the early years of the motion picture industry, Harold Lloyd was also a shrewd businessman and became the wealthiest man in Hollywood at the peak of his career. Perhaps more than any other major star of the silent era, his characters mirrored his times and captivated his contemporaries. His experiments with camera placement and motion were vital to the evolution of filmmaking techniques. This book includes a short biography of Lloyd and detailed information about all of his performances. The biography overviews his childhood, his adolescent stage career, his work in silent and talking pictures, his family life, and the work of his major contemporaries. A chapter on his film work includes entries for all of his shorts and features, including cameo roles and newsreels. Other chapters describe Lloyd's radio and television work, sheet music and recordings inspired by his films, and his many awards and honors. An annotated bibliography cites books, magazines, newspapers, oral histories, and interviews. Eleven photographs illustrate his work.
