Book Description
Information Retrieval (IR) has concentrated on the development of information management systems to support user retrieval from large collections of homogeneous textual material. A variety of approaches have been tried and tested with varying degrees of success over many decades of research. Hypertext (HT) systems, on the other hand, provide a retrieval paradigm based on browsing through a structured information space, following pre-defined connections between information fragments until an information need is satisfied, or appears to be. Information Retrieval and Hypertext addresses the confluence of the areas of IR and HT and explores the work done to date in applying techniques from one area, to the other leading to the development of `hypertext information retrieval' (HIR) systems. An important aspect of the work in IR/HT and in any user-centred information system is the emergence of multimedia information and such multimedia information is treated as an integral information type in this text. The contributed chapters cover the development of integrated hypertext information retrieval models, and the application of IR and HT techniques in hypertext construction and the approaches that can be taken in searching HIR systems. These chapters are complemented by two overview chapters covering, respectively, information retrieval and hypertext research and developments. Information Retrieval and Hypertext is important as it is the first text to directly address the combined searching/browsing paradigm of information discovery which is becoming so important in modern computing environments. It will be of interest to researchers and professionals working in a range of areas related to information discovery.

Book Description
This most unusual book results from the NATO Advanced Research Work shop, "Designing Hypertext/Hypermedia for Learning", held in Rottenburg am Neckar, FRO, from July 3-8, 1989. The idea for the workshop resulted from the burgeoning interest in hypertext combined with the frustrating lack of literature on leaming applications for hypertext. There was little evidence in 1988 that hypertext could successfully support learning out comes. A few projects were investigating hypertext for learning, but few conclusions were available and little if any advice on how to design hyper text for learning applications was available. Could hypertext support learning objectives? What mental processing requirements are unique to learning outcomes? How would the processing requirements of learning outcomes interact with unique user processing requirements of browsing and constructing hypertext? Should hypertext information bases be restruc tured to accommodate learning outcomes? Should the user interface be manipulated in order to support the task functionality of learning outcomes? Does the hypertext structure reflect the intellectual requirements of learning outcomes? What kinds of learning-oriented hypertext systems were being developed and what kinds of assumptions were these systems making? These and other questions demonstrated the need for this workshop. The workshop included presentations, hardware demonstrations, sharing and browsing of hypertexts, and much discussion about all of the above. These were the experiences that you, the reader of this book, unfortunately did not experience.

Book Description
Historical Information Science is an extensive review and bibliographic essay, backed by almost 6,000 citations, detailing developments in information technology since the advent of personal computers and the convergence of several social science and humanities disciplines in historical computing. Its focus is on the access, preservation, and analysis of historical information (primarily in electronic form) and the relationships between new methodology and instructional media, techniques, and research trends in library special collections, digital libraries, data archives, and museums.

Book Description
The recent evolution of western societies has been characterized by an increasing emphasis on information and communication. As the amount of available information increases, however, the user -- worker, student, citizen -- faces a new problem: selecting and accessing relevant information. More than ever it is crucial to find efficient ways for users to interact with information systems in a way that prevents them from being overwhelmed or simply missing their targets. As a result, hypertext systems have been developed as a means of facilitating the interactions between readers and text. In hypertext, information is organized as a network in which nodes are text chunks (e.g., lists of items, paragraphs, pages) and links are relationships between the nodes (e.g., semantic associations, expansions, definitions, examples -- virtually any kind of relation that can be imagined between two text passages). Unfortunately, the many ways in which these hypertext interfaces can be designed has caused a complexity that extends far beyond the processing abilities of regular users. Therefore, it has become widely recognized that a more rational approach based on a thorough analysis of information users' needs, capacities, capabilities, and skills is needed. This volume seeks to meet that need. From a user-centered perspective -- between systems and users -- this volume presents theoretical and empirical research on the cognitive processes involved in using hypertext. In so doing, it illustrates three main approaches to the design of hypertext systems: *cognitive, which examines how users process multilayered hypertext structures; *ergonomical, which explores how users interact with the design characteristics of hardware and software; and *educational, which studies the learning objectives, frequency and duration of hypertext sessions, type of reading activity, and the user's learning characteristics. This volume also tries to provide answers for the questions that have plagued hypertext research: *What is hypertext good for? *Who is hypertext good for? *If it is useful for learning and instruction, then what type? *What particular cognitive skills are needed to interact successfully with a hypertext system? Anyone interested in the fields of computer science, linguistics, psychology, education, and graphic design will find this volume intriguing, informative, and a definitive starting point for future research in the field of hypertext.

"In this insightful and readable volume, Landow explores the relationship between contemporary literary and social theory and the latest advances in computer software."-- "Voice Literary Supplement.""A useful book for understanding the effect technology is having on scholarship."-- "Semiotic Review of Books.""Landow 's ... presentation is measured, experiential, lucid, moderate, and sensible. He merely points out that the concept hypertext' lets us test some concepts associated with critical theory, and gracefully shows how the technology is contributing to reconfigurations of text, author, narrative, and (literary) education."-- "Post Modern Culture.""Good news for teachers who are not too sensitive about their intellectual authority... Bad news for print culture."-- "Times Literary Supplement"

Book Description
A collection of papers from the second UK conference on hypertext held at York University on 29-30 June 1989. This set of research papers surveys the state-of-the-art in applications of hypertext which permit non-sequential access to large knowledge bases. The topics covered include browsing and navigation, authoring, engineering and design of hypertext, hypertext in learning, design and information sciences. The book also looks at the more general issues involved in hypermedia. The book may be of interest to lecturers and researchers in computer science, industrial computer users and users of personal computers.

Book Description
The subject of hypertext and hypermedia has been witnessing a dramatic rise in interest over the last three years both from the academic and the industrial communities. This volume presents the proceedings of the European Conference on Hypertext (ECHT90) conference held in Paris in November 1990, where researchers, developers, and users were able to meet and discuss the theme of hypertext and hypermedia. This volume will be of interest to a broad spectrum of professionals ranging from pure theoreticians of hypergraphs and graph grammars via system developers for electronic publishing to end-users of hypertext applications such as medical information systems and computer aided design.
