- Abstract
- Almost all Web searches are carried out while the user is sitting at a conventional desktop computer connected to the Internet. Although online, handheld, mobile search offers new possibilities, the fast-paced, focused style of interaction may not be appropriate for all user search needs. The authors explore an alternative, relaxed style for Web searching that asynchronously combines an offline handheld computer and an online desktop personal computer. They discuss the role and utility of such an approach, present a tool to meet these user needs, and discuss its relation to other systems.

- Abstract
- Ahlgren, Jarneving, and. Rousseau review accepted procedures for author co-citation analysis first pointing out that since in the raw data matrix the row and column values are identical i,e, the co-citation count of two authors, there is no clear choice for diagonal values. They suggest the number of times an author has been co-cited with himself excluding self citation rather than the common treatment as zeros or as missing values. When the matrix is converted to a similarity matrix the normal procedure is to create a matrix of Pearson's r coefficients between data vectors. Ranking by r and by co-citation frequency and by intuition can easily yield three different orders. It would seem necessary that the adding of zeros to the matrix will not affect the value or the relative order of similarity measures but it is shown that this is not the case with Pearson's r. Using 913 bibliographic descriptions form the Web of Science of articles form JASIS and Scientometrics, authors names were extracted, edited and 12 information retrieval authors and 12 bibliometric authors each from the top 100 most cited were selected. Co-citation and r value (diagonal elements treated as missing) matrices were constructed, and then reconstructed in expanded form. Adding zeros can both change the r value and the ordering of the authors based upon that value. A chi-squared distance measure would not violate these requirements, nor would the cosine coefficient. It is also argued that co-citation data is ordinal data since there is no assurance of an absolute zero number of co-citations, and thus Pearson is not appropriate. The number of ties in co-citation data make the use of the Spearman rank order coefficient problematic.

- Rez. in: KO 33(2006) no.2, S.119-20 (S.S. Intner): "This survey of cataloging education around the world offers readers a rich menu of experiences, educational offerings, and approaches to the subject of cataloging education as it is currently practiced in 24 countries of the world, excluding the United States and Canada. The exclusion does not mean that English-speaking countries are entirely absent from the book, however. Two nations outside North America, South Africa (in one chapter) and Australia (in two chapters), are covered. The chapters are organized geographically, beginning with the African continent, and followed by several each under headings for Asia, Australia (two chapters), Europe, Latin America, and the Middle East. Nations whose cataloging education programs are described include (in order of presentation) Botswana, Nigeria, South Africa, China (both the People's Republic of China and Taiwan), India, Japan, South Korea, Australia, Austria and Germany (described together in one chapter), Poland, Slovenia, Spain, the British Isles (England, Scotland, and Wales), Argentina, Mexico, Peru, Egypt, Iran, Israel, and Saudi Arabia. As readers might expect, many chapters reflect common experiences among the countries, particularly regarding the proliferation of subjects in competition with cataloging and classification in library school curricula. There are also some common problems, such as dealing with the changes in education and training prompted by automation. Generally, computer-based cataloging is not a new issue anywhere, although in some areas of the world, catalogers still work with manual systems. Describing cataloging education in Nigeria, J. I. Iwe states: "... the card catalogue is still being used in all libraries, including the University of Calabar library where the only library school in the state exists (p. 33)." In other places, computer infrastructure has developed to a level that supports coursework online. As Linda M. Cloete writes, "The ultimate goal of the training resource program is to develop an online, fully interactive course: an online virtual cataloging classroom (p. 66)."
The eternal debate in the teaching of cataloging over theory versus practice emerges in this volume. As Li Si suggests in describing cataloging education in the People's Republic of China, the matter might be laid at the door of the faculty, stating, "Although the majority of teaching faculty members in the library and information science programs have a solid theoretical foundation from their school education and training, they do not normally possess practical work experience in their field of specialty and they are not familiar with the application of technologies in the field. In order to enhance their practical skills, these faculty members should be given the opportunity to work in libraries... This way, they would be able to put theory into practice and gain rich, practical field experience, thus improving the relevance and quality of their teaching (p. 97)." One wonders how warmly faculty members would welcome that kind of opportunity! On the other hand, in many places, onthe-job training is weak, as Shoichi Taniguchi describes it in Japan, "on the job training and continuing education are neither encouraged nor promoted (p. 132)." Among the most interesting and important aspects of this book are the tables of hard data it presents. Almost every chapter reports on surveys done by the authors on the state of library education in general and/or the kinds of offerings in cataloging and classification available within their countries. Some authors also include statistics on the numbers of persons receiving certificates, diplomas, and/or master's degrees, which is useful in understanding the different levels of expertise being developed over time. While one could argue that there are gaps in coverage, with large, influential countries such as France and Italy in Europe, Brazil, Bolivia, and Chile in South America, and Thailand and Myanmar in Asia, left out of the book, for the most part there is good representation from different parts of the globe. Education for Library Cataloging is a good choice as a textbook for coursework in International Librarianship as well as a primer in what to expect if one's information center is affiliated with partners outside the United States and Canada. This book should be seen as an important "must read" for all library students and practitioners concerned about issues of increasing globalization in bibliographic control. It is highly recommended."
