Abstract

Aimed at students and professionals within Library and Information Services (LIS), this book is about the power and potential of ontologies to enhance the electronic search process. The book will compare search strategies and results in the current search environment and demonstrate how these could be transformed using ontologies and concept searching. Simple descriptions, visual representations, and examples of ontologies will bring a full understanding of how these concept maps are constructed to enhance retrieval through natural language queries. Readers will gain a sense of how ontologies are currently being used and how they could be applied in the future, encouraging them to think about how their own work and their users' search experiences could be enhanced by the creation of a customized ontology. Key Features Written by a librarian, for librarians (most work on ontologies is written and read by people in computer science and knowledge management) Written by a librarian who has created her own ontology and performed research on its capabilities Written in easily understandable language, with concepts broken down to the basics The Author Ms. King is the Information Specialist at the Center on Media and Child Health at Children's Hospital Boston. She is a graduate of Smith College (B.A.) and Simmons College (M.L.I.S.). She is an active member of the Special Libraries Association, and was the recipient of the 2005 SLA Innovation in Technology Award for the creation of a customized media effects ontology used for semantic searching. Readership The book is aimed at practicing librarians and information professionals as well as graduate students of Library and Information Science.

Abstract

After 25 years of service, this professional text has been updated in line with developments in the field of library science. Since the seventh edition of this standard text was published in 1985, there have been changes in virtually every area of bibliographic control. "AACR2 Revised" (AACR2R) has been implemented; new editions of or supplements to LCSH, LC classification, and DDC, and "Sears" have appeared; OCLC has adopted the PRISM format; and networking and online catalogues have become a way of life. Taylor addresses these and other changes in this edition. Consequently, many chapters of this text are entirely new, such as "Cataloguing in Context" and "Subject Arrangement of Library Materials", or fully revised such as "Development of Cataloguing Codes", which has been expanded to show the continuity in the development leading to publication of AACR2R. Two appendices have been added: an introduction to USMARC format and instructions for typing catalogue cards, including a detailed analysis of the punctuation and spacing to be used when conforming to the International Standard Bibliographic Description (ISBD).

Abstract

More and more libraries, archives, and museums are creating online collections of digitized resources. Where can those charged with organizing these new collections turn for guidance on the actual practice of metadata design and creation? "Metadata for Digital Collections: A How-to-do-it Manual" is suitable for libraries, archives, and museums. This practical, hands-on volume will make it easy for readers to acquire the knowledge and skills they need, whether they use the book on the job or in a classroom. Author Steven Miller introduces readers to fundamental concepts and practices in a style accessible to beginners and LIS students, as well as experienced practitioners with little metadata training. He also takes account of the widespread use of digital collection management systems such as CONTENTdm. Rather than surveying a large number of metadata schemes, Miller covers only three of the schemes most commonly used in general digital resource description, namely, Dublin Core, MODS, and VRA. By limiting himself, Miller is able to address the chosen schemes in greater depth. He is also able to include numerous practical examples that clarify common application issues and challenges. He provides practical guidance on applying each of the Dublin Core elements, taking special care to clarify those most commonly misunderstood. The book includes a step-by-step guide on how to design and document a metadata scheme for local institutional needs and for specific digital collection projects. The text also serves well as an introduction to broader metadata topics, including XML encoding, mapping between different schemes, metadata interoperability and record sharing, OAI harvesting, and the emerging environment of Linked Data and the Semantic Web, explaining their relevance to current practitioners and students. Each chapter offers a set of exercises, with suggestions for instructors. A companion website includes additional practical and reference resources.
