Rez. in: JASIST 55(2004) no.1, S.90-91 (N. Rhodes): "The recent near-exponential increase in XML-based technologies has exposed a gap between these technologies and those that are concerned with more fundamental data management issues. This very comprehensive and well-organized book has quite neatly filled the gap, thus achieving most of its stated intentions. The target audiences are database and XML professionals wishing to combine XML with modern database technologies and such is the breadth of scope of this book (hat few would not find it useful in some way. The editors have assembled a collection of chapters from a wide selection of industry heavyweights and as with most books of this type, it exhibits many disparate styles but thanks to careful editing it reads well as a cohesive whole. Certain sections have already appeared in print elsewhere and there is a deal of corporate flag-waving but nowhere does it become over-intrusive. The preface provides only the very brietest of introductions to XML but instead sets the tone for the remainder of the book. The twin terms of data- and document-centric XML (Bourret, 2003) that have achieved so much recent currency are re-iterated before XML data management issues are considered. lt is here that the book's aims are stated, mostly concerned with the approaches and features of the various available XML data management solutions. Not surprisingly, in a specialized book such as this one an introduction to XML consists of a single chapter. For issues such as syntax, DTDs and XML Schemas the reader is referred elsewhere, here, Chris Brandin provides a practical guide to achieving good grammar and style and argues convincingly for the use of XML as an information-modeling tool. Using a well-chosen and simple example, a practical guide to modeling information is developed, replete with examples of the pitfalls. This brief but illuminating chapter (incidentally available as a "taster" from the publisher's web site) notes that one of the most promising aspects of XML is that applications can be built to use a single mutable information model, obviating the need to change the application code but that good XML design is the basis of such mutability.

However, for well over a century, major libraries in developed nations have been engaging in sophisticated measure of their operations, and thoughtful scholars have been involved along the way; if no "unified theory" has emerged thus far, why would it happen in the near future? What if "libraries" are a historicallydetermined conglomeration of distinct functions, some of which are much less important than others? It is telling that McGrath cites as many studies an brittle paper as he does investigations of reference services among his constellation of measurable services, even while acknowledging that the latter (as an aspect of "circulation") is more "essential." If one were to include in a unified theory similar phenomena outside of libraries-e.g., what happens in bookstores and WWW searches-it can be seen how difficult a coordinated explanation might become. Ultimately the value of McGrath's chapter is not in convincing the reader that a unified theory might emerge, but rather in highlighting the best in recent studies that examine library operations, identifying robust conclusions, and arguing for the necessity of clarifying and coordinating common variables and units of analysis. McGrath's article is one that would be useful for a general course in LIS methodology, and certainly for more specific lectures an the evaluation of libraries. Fra going to focus most of my comments an the remaining articles about theory, rather than the others that offer empirical results about the growth or quality of literature. I'll describe the latter only briefly. The best way to approach this issue is by first reading McKechnie and Pettigrew's thorough survey of the "Use of Theory in LIS research." Earlier results of their extensive content analysis of 1, 160 LIS articles have been published in other journals before, but is especially pertinent here. These authors find that only a third of LIS literature makes overt reference to theory, and that both usage and type of theory are correlated with the specific domain of the research (e.g., historical treatments versus user studies versus information retrieval). Lynne McKechnie and Karen Pettigrew identify four general sources of theory: LIS, the Humanities, Social Sciences and Sciences. This approach makes it obvious that the predominant source of theory is the social sciences (45%), followed by LIS (30%), the sciences (19%) and the humanities (5%) - despite a predominance (almost 60%) of articles with science-related content. The authors discuss interdisciplinarity at some length, noting the great many non-LIS authors and theories which appear in the LIS literature, and the tendency for native LIS theories to go uncited outside of the discipline. Two other articles emphasize the ways in which theory has evolved. The more general of three two is Jack Glazier and Robert Grover's update of their classic 1986 Taxonomy of Theory in LIS. This article describes an elaborated version, called the "Circuits of Theory," offering definitions of a hierarchy of terms ranging from "world view" through "paradigm," "grand theory" and (ultimately) "symbols." Glazier & Grover's one-paragraph example of how theory was applied in their study of city managers is much too brief and is at odds with the emphasis an quantitative indicators of literature found in the rest of the volume. The second article about the evolution of theory, Richard Smiraglia's "The progress of theory in knowledge organization," restricts itself to the history of thinking about cataloging and indexing. Smiraglia traces the development of theory from a pragmatic concern with "what works," to a reliance an empirical tests, to an emerging flirtation with historicist approaches to knowledge.
