Abstract

Let us start with a simple scenario: a man asks a woman "how high is Mount Everest?" The woman replies "29,029 feet." Nothing could be simpler. Now let us suppose that rather than standing in a room, or sitting on a bus, the man is at his desk and the woman is 300 miles away with the conversation taking place using e-mail. Still simple? Certainly--it happens every day. So why all the bother about digital (virtual, electronic, chat, etc.) reference? If the man is a pilot flying over Mount Everest, the answer matters. If you are a lawyer going to court, the identity of the woman is very important. Also, if you ever want to find the answer again, how that transaction took place matters a lot. Digital reference is a deceptively simple concept on its face: "the incorporation of human expertise into the information system." This lecture seeks to explore the question of how human expertise is incorporated into a variety of information systems, from libraries, to digital libraries, to information retrieval engines, to knowledge bases. What we learn through this endeavor, begun primarily in the library context, is that the models, methods, standards, and experiments in digital reference have wide applicability. We also catch a glimpse of an unfolding future in which ubiquitous computing makes the identification, interaction, and capture of expertise increasingly important. It is a future that is much more complex than we had anticipated. It is a future in which documents and artifacts are less important than the contexts of their creation and use.

Abstract

A research agenda for the study of digital reference is presented. The agenda stems from a research symposium held at Harvard University, Boston, Massachusetts in August 2002. The agenda defines digital reference as "the use of human intermediation to answer questions in a digital environment." The agenda also proposes the central research question in digital reference: "How can human expertise be effectively and efficiently incorporated into information systems to answer user questions?" The definition and question are used to outline a research agenda centered an how the exploration of digital reference relates to other fields of inquiry.

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.
