The study of the mapping class group Mod(S) is a classical topic that is experiencing a renaissance. It lies at the juncture of geometry, topology, and group theory. This book explains as many important theorems, examples, and techniques as possible, quickly and directly, while at the same time giving full details and keeping the text nearly self-contained. The book is suitable for graduate students. A Primer on Mapping Class Groups begins by explaining the main group-theoretical properties of Mod(S), from finite generation by Dehn twists and low-dimensional homology to the Dehn-Nielsen-Baer theorem. Along the way, central objects and tools are introduced, such as the Birman exact sequence, the complex of curves, the braid group, the symplectic representation, and the Torelli group. The book then introduces Teichmüller space and its geometry, and uses the action of Mod(S) on it to prove the Nielsen-Thurston classification of surface homeomorphisms. Topics include the topology of the moduli space of Riemann surfaces, the connection with surface bundles, pseudo-Anosov theory, and Thurston's approach to the classification.
A Practical Guide to Library of Congress Classification is a hands-on introduction to LC Classification. The book examines each part of the LCC call number and how it is assembled and guides the reader through each step of finding and constructing LCC class numbers in Classification Web (the primary resource used to access LCC). Chapter coverage is complete: 1. Introduction 2. Library of Congress Classification in a Nutshell 3. Breaking Down the Library of Congress Call Number 4. Dates 5. Cutters 6. LCC in Classification Web 7. Basic LCC Call Number Building 8. Advanced Call Number Building 9. Classifying Fiction in LCC 10. Finding and using LCC Resources Exercises at the end of most chapters give readers immediate practice with what they just learned. Answers to the exercises are provided at the end of the book. By the end of the book readers will be able to build an LCC call number on their own.
A detailed introduction to the methods used by ecologists--classification and ordination--to clarify and interpret large, unwieldy masses of multivariate field data. Permits ecologists to understand, not just mechanically use, pre-packaged programs for multivariate analysis. Demonstrates these techniques using artificial data simple enough for every analytical step to be understood.
This book, first published in 1931, presents a survey of librarianship by some of its leading theorists of the early twentieth century, a time of rapid library expansion following the Library Act of 1919. The entire field of Library service was undergoing review and experiment, with little remaining unchanged, and this volume details some of the new and modern practices then being adopted.
Making the Move to RDA: A Self-Study Primer for Catalogers is aimed at catalogers working in the MARC environment who currently create records using AACR2 and need to transition to using the new standard, Resource Description and Access (RDA). Since both RDA’s structure and content differ from AACR2 in many respects, this primer details the development and rationale for RDA as well as its intended goals, principles, and objectives. It then explains RDA’s theoretical underpinnings—collectively known as the FRBR Family of Models. Framing the text along these lines provides readers the context for understanding the similarities and differences between AACR2 and RDA, both in terms of content and structure. With this foundation in place, the book takes the reader on a survey of RDA elements used to describe bibliographic and authority records and demonstrates how the MARC code has been expanded to accommodate new elements. Finally, it leads the reader field-by-field through MARC bibliographic records for book and non-book resources as well as through authority records for works, expressions, persons, families, and corporate bodies, describing the similarities and differences between AACR2 and RDA for each field. Examples are provided throughout the text to help the reader visualize the concepts presented.
Vietnam was America's most divisive and unsuccessful foreign war. It was also the first to be televised and the first of the modern era fought without military censorship. From the earliest days of the Kennedy-Johnson escalation right up to the American withdrawal, and even today, the media's role in Vietnam has continued to be intensely controversial. The "Uncensored War" gives a richly detailed account of what Americans read and watched about Vietnam. Hallin draws on the complete body of the New York Times coverage from 1961 to 1965, a sample of hundreds of television reports from 1965-73, including television coverage filmed by the Defense Department in the early years of the war, and interviews with many of the journalists who reported it, to give a powerful critique of the conventional wisdom, both conservative and liberal, about the media and Vietnam. Far from being a consistent adversary of government policy in Vietnam, Hallin shows, the media were closely tied to official perspectives throughout the war, though divisions in the government itself and contradictions in its public relations policies caused every administration, at certain times, to lose its ability to "manage" the news effectively. As for television, it neither showed the "literal horror of war," nor did it play a leading role in the collapse of support: it presented a highly idealized picture of the war in the early years, and shifted toward a more critical view only after public unhappiness and elite divisions over the war were well advanced.
