Presents suggested headings appropriate for use in the catalogs of small and medium-sized libraries, and provides patterns and instructions for adding new headings as they are required. The seventeenth edition features a revision of headings for the native peoples of the Western Hemisphere, as well as many new subdivisions.

The first comprehensive theoretical treatise on Library of Congress subject headings, this important book provides an analysis of the Library of Congress subject heading system and its application. Library of Congress Subject Headings aims to help improve the clarity of the system, increase consistency and arrangement, increase the number of effective access points, facilitate the interaction of the system with the computer, and generally to make the Library of Congress subject heading system and its application of even greater value to the cataloger and the user. Practicing catalogers, library school personnel, advanced students, and any professional who is very knowledgeable about and seriously interested in Library of Congress subject headings will want to read this highly acclaimed volume.Author William Studwell includes theoretical, conceptual, and philosophical considerations based on 25 years of everyday practical cataloging and indexing work and the knowledge gained from theoretical research for the more than two dozen articles on subject cataloging that he has written in the last decade. He presents thought-provoking, often controversial material in three parts. The first section, "The System," deals with the basic philosophical foundations of LC subject headings. Thirty-two "principles"--guidelines and suggestions are offered along with detailed explanations, examples, and their relationships to other principles. The second section, "Application," focuses on the matters of subject cataloging practice, or interpretation and application of LC subject headings. The third section, "The Future," looks ahead to future issues relating to subject cataloging, such as the development of a theoretical subject heading code, the interface of LC subject headings with the computer, and some speculation as to the role and nature of LC subject headings in the years to come.

Everything we need to know about metadata, the usually invisible infrastructure for information with which we interact every day. When “metadata” became breaking news, appearing in stories about surveillance by the National Security Agency, many members of the public encountered this once-obscure term from information science for the first time. Should people be reassured that the NSA was “only” collecting metadata about phone calls—information about the caller, the recipient, the time, the duration, the location—and not recordings of the conversations themselves? Or does phone call metadata reveal more than it seems? In this book, Jeffrey Pomerantz offers an accessible and concise introduction to metadata. In the era of ubiquitous computing, metadata has become infrastructural, like the electrical grid or the highway system. We interact with it or generate it every day. It is not, Pomerantz tell us, just “data about data.” It is a means by which the complexity of an object is represented in a simpler form. For example, the title, the author, and the cover art are metadata about a book. When metadata does its job well, it fades into the background; everyone (except perhaps the NSA) takes it for granted. Pomerantz explains what metadata is, and why it exists. He distinguishes among different types of metadata—descriptive, administrative, structural, preservation, and use—and examines different users and uses of each type. He discusses the technologies that make modern metadata possible, and he speculates about metadata's future. By the end of the book, readers will see metadata everywhere. Because, Pomerantz warns us, it's metadata's world, and we are just living in it.
