The changes brought about by the World Wide Web and the explosion of electronic media have called into question many of the assumptions on which national bibliographies have been founded. The need was growing of a route map to navigate through unchartes territories. After a preparation period of several years, IFLAAs Bibliography Section endorsed this large set of guidelines. They seek to help national bibliographic agencies improve their bibliographic services. Many examples and references are included.

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.

This book constitutes the refereed proceedings of the 20th International Conference on Asia-Pacific Digital Libraries, ICADL 2018, held in Hamilton, New Zealand, in November 2018. The 20 full, 6 short, and 11 work in progress papers presented in this volume were carefully reviewed and selected from 77 submissions. The papers were organized in topical sections named: topic modeling and semantic analysis; social media, web, and news; heritage and localization; user experience; digital library technology; and use cases and digital librarianship.

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.
