Footnote

The discussion of available tools is excellent and quite comprehensive. This will prove very helpful to practitioners and students setting out to learn about the world of storage, retrieval, and indexing of images. The author's simple, straightforward writing style is praiseworthy, since it will help those just starting out in the field to grasp the material quickly. It will also contribute to understanding an the part of readers from other language communities who have English as a second language. Although this book discusses a number of complex topics, the author has succeeded in making the treatment of them eminently understandable. Chapter 6 will prove particularly useful to researchers in the area, many more of whom are needed, and especially to graduate students thinking about undertaking a doctoral programme in the area of image management. The author provides a research agenda which describes a number of areas in which research is needed, including a number of research questions to work on. She also includes her wish list, which "represents a personal perspective, and is offered ... as food for thought and future discussion" (p. 267). Jörgensen feels her book will soon be out of date, and indeed, that in writing the book she has been "pursuing a moving target" (p. 4). Since there is so muck work going an in the broad field of image retrieval (although not enough in the area of information science), new discoveries will be made, new issues we hadn't thought about before will come to light, new methods and standards for managing picture databases will be developed, and new approaches will surely come along. However, I'm not so sure this book will be out of date any time soon, since it serves as a record of arriving at a plateau, a point at which the knowledge accumulated to date has been gathered, recorded, and presented as a portrait of what has been achieved and of where we are now. At the very least, then, Jörgensen's book will remain as a solid record of the research to date. More immediately, it will serve as a guide to what we should be doing now, and to the next steps that need to be taken."
