    The most common definition for metadata is "data about data." What metadata does is provide schemes for describing, organizing, exchanging, and receiving information over networks. The authors explain how metadata is used to describe resources by tagging item attributes like author, title, creation date, key words, file formats, compression, etc. The most well known scheme is MARC, but other schemes are developing for creating and managing digital collections, such as XML, TEI, EAD, and Dublin Core. The authors also do a good job of describing the difference between metadata and mark-up languages like HTML. The next two chapters discuss developing, designing, and providing access to a digital collection. In Chapter Six, "Developing and Designing Systems for Sharing Digital Resources," the authors examine a number of issues related to designing a shared collection. For instance, one issue the authors examine is interoperability. The authors stress that when designing a digital collection the creators should take care to ensure that their collection is "managed in such a way as to maximize opportunities for exchange and reuse of information, whether internally or externally" (p. 140). As a complement to Chapter Six, Chapter Seven, "Portals and Personalization: Mechanisms for End-user Access," focuses an the other end of the process; how the collection is used once it is made available. The majority of this chapter concentrates an the use of portals or gateways to digital collections. One example the authors use is MyLibrary@NCState, which provides the university community with a flexible user-drive customizable portal that allows user to access remote and local resources. The work logically concludes with a chapter an preservation and a chapter an the evolving role of librarians. Chapter Eight, "Preservation," is a thought-provoking discussion an preserving digital data and digitization as a preservation technique. The authors do a good job of relaying the complexity of preservation issues in a digital world in a single chapter. While the authors do not answer their questions, they definitely provide the reader wich some things to ponder. The final chapter, "Digital Librarians: New Roles for the Information Age," outlines where the authors believe librarianship is headed. Throughout the work they stress the role of the librarian in the digital world, but Chapter Nine really brings the point home. As the authors stress, librarians have always managed information and as experienced leaders in the information field, librarians are uniquely suited to take the digital bull by the horns. Also, the role of the librarian and what librarians can do is growing and evolving. The authors suggest that librarians are likely to move into rotes such as knowledge mediator, information architect, hybrid librarian-who brings resources and technologies together, and knowledge preserver. While these librarians must have the technical skills to cope with new technologies, the authors also state that management skills and subject skills will prove equally important.

    Rez. in: JASIST. 58(2007) no.6., S.909-910 (A.D. Petrou): "A division in metadata definitions for physical objects vs. those for digital resources offered in Chapter 1 is punctuated by the use of broader, more inclusive metadata definitions, such as data about data as well as with the inclusion of more specific metadata definitions intended for networked resources. Intertwined with the book's subject matter, which is to "distinguish traditional cataloguing from metadata activity" (5), the authors' chosen metadata definition is also detailed on page 5 as follows: Thus while granting the validity of the inclusive definition, we concentrate primarily on metadata as it is most commonly thought of both inside and outside of the library community, as "structured information used to find, access, use and manage information resources primarily in a digital environment." (International Encyclopedia of Information and Library Science, 2003) Metadata principles discussed by the authors include modularity, extensibility, refinement and multilingualism. The latter set is followed by seven misconceptions about metadata. Two types of metadata discussed are automatically generated indexes and manually created records. In terms of categories of metadata, the authors present three sets of them as follows: descriptive, structural, and administrative metadata. Chapter 2 focuses on metadata for communities of practice, and is a prelude to content in Chapter 3 where metadata applications, use, and development are presented from the perspective of libraries. Chapter 2 discusses the emergence and impact of metadata on organization and access of online resources from the perspective of communities for which such standards exist and for the need for mapping one standard to another. Discussion focuses on metalanguages, such as Standard Generalized Markup Language (SGML) and eXtensible Markup Language (XML), "capable of embedding descriptive elements within the document markup itself' (25). This discussion falls under syntactic interoperability. For semantic interoperability, HTML and other mark-up languages, such as Text Encoding Initiative (TEI) and Computer Interchange of Museum Information (CIMI), are covered. For structural interoperability, Dublin Core's 15 metadata elements are grouped into three areas: content (title, subject, description, type, source, relation, and coverage), intellectual property (creator, publisher, contributor and rights), and instantiation (date, format, identifier, and language) for discussion.
