The purpose of authority control is to ensure consistency in representing a value - a name of a person, a place name, or a term or code representing a subject - in the elements used as access points in information retrieval. The primary purpose of this study is to produce a framework that will provide a clearly stated and commonly shared understanding of what the subject authority data/record/file aims to provide information about, and the expectation of what such data should achieve in terms of answering user needs.

The first comprehensive exploration of the development and use of the International Federation of Library Associations and Institutions' (IFLA) newly released model for subject authority data, covering everything from the rationale for creating the model to practical steps for implementing it. FRSAD: Conceptual Modeling of Aboutness explores the full dimensions of the IFLA's Functional Requirements for Subject Authority Data model, showing how putting the model to work can ease information sharing across systems, domains, and environments. Written by three leading members of the IFLA working group that developed the model, FRSAD moves from the theoretical foundations of knowledge organization to a complete conceptual overview of the model, to specific working guidelines for its implementation. The book is filled with insights into the factors driving the model's development, as well as numerous illustrative examples of its practical applications in real-world settings. It also focuses on the benefits of using the model when developing knowledge organization systems (KOS) within the library domain and beyond.

Since 1998 when FRBR (Functional Requirements for Bibliographic Records) was first published by IFLA, the effort to develop and apply FRBR has been extended in many innovative and experimental directions. Papers in this volume explain and expand upon the extended family of FRBR models including Functional Requirements for Authority Data (FRAD), Functional Requirements for Subject Authority Data (FRSAD), and the object-oriented version of FRBR known as FRBRoo. Readers will learn about dialogues between the FRBR Family and other modeling technologies, specific implementations and extensions of FRBR in retrieval systems, catalog codes employing FRBR, a wide variety of research that uses the FRBR model, and approaches to using FRBR for the Semantic Web. Librarians of all stripes as well as library and information science students and researchers can use this volume to bring their knowledge of the FRBR model and its implementation up to date. This book was published as a special issue of Cataloging & Classification Quarterly.

The Encyclopedia of Library and Information Sciences, comprising of seven volumes, now in its fourth edition, compiles the contributions of major researchers and practitioners and explores the cultural institutions of more than 30 countries. This major reference presents over 550 entries extensively reviewed for accuracy in seven print volumes or online. The new fourth edition, which includes 55 new entires and 60 revised entries, continues to reflect the growing convergence among the disciplines that influence information and the cultural record, with coverage of the latest topics as well as classic articles of historical and theoretical importance.

In this issue of Library Technology Reports, Karen Coyle updates readers on the development of fundamental resources such as standards, data elements, and term lists, showing how they fit together.

In a networked and globalized world of information the form of national bibliographies may have changed, however their major function remains unchanged: to inform about a country’s publication landscape, its cultural and intellectual heritage. Subject access offers a major route into this landscape providing information about the dispersion of publications in specific fields of knowledge and topics contained in a particular national publishing output. The Guidelines for Subject Access in National Bibliographies give graded recommendations concerning subject indexing policies for national bibliographic agencies and illustrating various policies by providing best practice examples.
