1Pomerantz, J.: Metadata.

(The MIT Press essential knowledge series)
Abstract: When "metadata" became breaking news, appearing in stories about surveillance by the National Security Agency, many members of the public encountered this once-obscure term from information science for the first time. Should people be reassured that the NSA was "only" collecting metadata about phone calls -- information about the caller, the recipient, the time, the duration, the location -- and not recordings of the conversations themselves? Or does phone call metadata reveal more than it seems? In this book, Jeffrey Pomerantz offers an accessible and concise introduction to metadata. In the era of ubiquitous computing, metadata has become infrastructural, like the electrical grid or the highway system. We interact with it or generate it every day. It is not, Pomerantz tell us, just "data about data." It is a means by which the complexity of an object is represented in a simpler form. For example, the title, the author, and the cover art are metadata about a book. When metadata does its job well, it fades into the background; everyone (except perhaps the NSA) takes it for granted. Pomerantz explains what metadata is, and why it exists. He distinguishes among different types of metadata -- descriptive, administrative, structural, preservation, and use -- and examines different users and uses of each type. He discusses the technologies that make modern metadata possible, and he speculates about metadata's future. By the end of the book, readers will see metadata everywhere. Because, Pomerantz warns us, it's metadata's world, and we are just living in it.

2Pomerantz, J. ; Marchionini, G.: ¬The digital library as place.
In: Journal of documentation. 63(2007) no.4, S.505-533.
Abstract: Purpose - The purpose of this paper is to present a high-level investigation of the physical-conceptual continuum occupied by both digital and physical libraries. Design/methodology/approach - A framework is provided for thinking about the notions of place and library. The issue of materials and the ideas they represent is considered. Places for people are considered, including issues of people's sense of place in physical and digital spaces. The issue of physical and digital spaces as places for work, collaboration, and community-building is considered. Findings - As more digital libraries are built, and as more physical libraries offer electronic access to parts of their collection, two trends are likely to result: the role of the library as a storage space for materials will become decreasingly important; and the role of the library as a space for users, for individual and collaborative work, and as a space for social activity, will become increasingly important. Research limitations/implications - Digital libraries are unable to fulfill some of the functions of the physical library as physical spaces, but are able to offer functions beyond what the physical library can offer as cognitive spaces. Practical implications - Areas of likely future development for digital libraries are suggested, as vehicles for enhancing cognitive space by augmenting representations of ideas in materials. Originality/value - This paper argues that in many ways digital libraries really are places in the conceptual sense, and will continue to broaden and enrich the roles that libraries play in people's lives and in the larger social milieu.
3Pomerantz, J.: ¬A linguistic analysis of question taxonomies.
In: Journal of the American Society for Information Science and Technology. 56(2005) no.7, S.715-728.
Abstract: Recent work in automatic question answering has called for question taxonomies as a critical component of the process of machine understanding of questions. There is a long tradition of classifying questions in library reference services, and digital reference services have a strong need for automation to support scalability. Digital reference and question answering systems have the potential to arrive at a highly fruitful symbiosis. To move towards this goal, an extensive review was conducted of bodies of literature from several fields that deal with questions, to identify question taxonomies that exist in these bodies of literature. In the course of this review, five question taxonomies were identified, at four levels of linguistic analysis.

4Pomerantz, J.: ¬A conceptual framework and open research questions for chat-based reference service.
In: Journal of the American Society for Information Science and Technology. 56(2005) no.12, S.1288-1302.
Abstract: This article seeks to shift the literature an chat-based reference services beyond the current spate of case studies and discussions of emerging standards and best practices in providing chat-based reference, to a higher level of discussion an the creation and discussion of theoretical frameworks to unite these standards and practices. The article explores the varlous steps in the process of providing synchronous, chat-based reference, as well as issues involved in providing such service at each step. The purpose of this exploration is twofold: First, this article presents some open research questions at each step in the process of providing chatbased reference service. Second, the entire process of providing chat-based reference is viewed as a whole, and a model of the provision of chat-based reference service is developed at a high level of abstraction. lt is hoped that this model may serve as a conceptual framework for future discussions of and development of applications for chat-based reference.

5Pomerantz, J. ; Nicholson, S. ; Belanger, Y. ; Lankes, R.D.: ¬The current state of digital reference : validation of a general digital reference model through a survey of digital reference services.
In: Information processing and management. 40(2004) no.2, S.347-363.
Abstract: This paper describes a study conducted to determine the paths digital reference services take through a general process model of asynchronous digital reference. A survey based on the general process model was conducted; each decision point in this model provided the basis for at least one question. Common, uncommon, and wished-for practices are identified, as well as correlations between characteristics of services and the practices employed by those services. Identification of such trends has implications for the development of software tools for digital reference. This study presents a snapshot of the state-of-the-art in digital reference as of late 2001- early 2002, and validates the general process model of asynchronous digital reference.

7Peek, R. ; Pomerantz, J. ; Paling, S.: ¬The traditional scholarly journal publishers legitimize the Web.
In: Journal of the American Society for Information Science. 49(1998) no.11, S.983-989.
Abstract: This article examines the entry of the major academic publishing houses into the WWW publishing. The study identified that during 1997, traditional academic publishers made significant commitments to putting tables of content, abstracts, and the full-text of their print journals on the Web. At the same time, new services and organizations emerged that could ultimately compete with, or eliminate, the need for certain segments of the industry. The authors suggest that these early experiments in Web publishing began unevenly with areas that needed improvement. The article concludes with a discussion about the implications of the traditional academic publisher's presence on the Web
