- Abstract
- For laypeople, searching online health information resources can be challenging due to topic complexity and the large number of online sources with differing quality. The goal of this article is to examine, among all the available online sources, which online sources laypeople select to address their health-related information needs, and whether or how much the severity of a health condition influences their selection. Twenty-four participants were recruited individually, and each was asked (using a retrieval system called HIS) to search for information regarding a severe health condition and a mild health condition, respectively. The selected online health information sources were automatically captured by the HIS system and classified at both the website and webpage levels. Participants' selection behavior patterns were then plotted across the whole information-seeking process. Our results demonstrate that laypeople's source selection fluctuates during the health information-seeking process, and also varies by the severity of health conditions. This study reveals laypeople's real usage of different types of online health information sources, and engenders implications to the design of search engines, as well as the development of health literacy programs.

- Abstract
- A unique collection of historical material covering the lives and events of an English village between 1400 and 1750 has been made available via a WWW enabled information retrieval system. Since the expected readership of the documents ranges from school children to experienced researchers, providing this information in an easily accessible form has offered many challenges requiring tools to aid searching and browsing. The file structure of the document collection was replaced by an database, enabling query results to be presented on the fly. A Java interface displays each user's context in a form that allows for easy and intuitive relevance feedback

- Abstract
- After modeling expert user needs with regard to intellectual property information, we analyze and compare the main providers in this specific information area (Thomson DIALOG, Esp@cenet by the European Patent Office, Questel-Orbit, and STN International) in terms of system content and system functionality. The key question is whether the main providers are able to satisfy these expert user needs. For patent information, some special retrieval features such as chemical structure search (including Markush search), patent family references and citations search, biosequence search, and basic informetric functionality such as ranking, mapping, and visualization of information flows are realized. Considering the results of information science research, the practice of patent information shows unexhausted improvement opportunities (e.g., the application of bibliographic patent coupling and co-patent-citation for mapping patents, patent assignees, and technology specialties). For trademark search, users need multiple truncated search (realized) as well as phonetic search and image retrieval (not realized yet).

- Abstract
- The proliferation of electronic information sources has added new dimensions to building library reference collections. As reference librarians select titles for their collections, they must also choose the most appropriate medium. For some information the choices include print, microforms, CD-ROM databases, online hosts, or locally mounted databases. Factors involved in the selection of the appropriate medium include database costs, licensing agreements, hardware/software requirements, retrieval modes, system capabilities and information transfer. Integrating the new services into existing structures so that library users can derive the maximum benefit from the availability of the databases is a primary concern

- Abstract
- Seit 3. Juli 2006 stellt das ZPID eine verbesserte Suchoberfläche für die Recherche in der bibliographischen Psychologie-Datenbank PSYNDEX zur Verfügung. Hauptmerkmal der neuen Version 1.1 des 'ZPID-Retrieval für PSYNDEX' ist die Einbindung von 'PSYNDEX Terms', dem kontrollierten Wortschatz der psychologischen Fachsprache. PSYNDEX Terms basiert auf dem 'Thesaurus of Psychological Index Terms' der American Psychological Association (APA) und enthält im Moment über 5.400 Deskriptoren. Zu jedem Deskriptor werden ggf. Oberbegriffe, Unterbegriffe und verwandte Begriffe angezeigt. Wer die Suchoberfläche nutzt, kann entweder im Thesaurus blättern oder gezielt nach Thesaurusbegriffen suchen. Kommt der eigene frei gewählte Suchbegriff nicht im Thesaurus vor, macht das System selbsttätig Vorschläge für passende Thesaurusbegriffe. DerThesaurus ist komplett zweisprachig (deutsch/englisch) implementiert, sodass er auch als Übersetzungshilfe dient. Weitere Verbesserungen der Suchoberfläche betreffen die Darstellbarkeit in unterschiedlichen Web-Browsern mit dem Ziel der Barrierefreiheit, die Erweiterung der OnlineHilfe mit Beispielen für erfolgreiche Suchstrategien, die Möglichkeit, zu speziellen Themen vertiefte Informationen abzurufen (den Anfang machen psychologische Behandlungsprogramme) und die Bereitstellung eines Export-Filters für EndNote. Zielgruppe des ZPID-Retrieval sind Einzelpersonen, die keinen institutionellen PSYNDEX-Zugang, z.B. am Campus einer Universität, nutzen können. Sie können das kostenpflichtige Retrieval direkt online erwerben und werden binnen weniger Minuten freigeschaltet. Kunden mit existierendem Vertrag kommen automatisch in den Genuss der verbesserten Suchoberfläche.

- Abstract
- This study analyzes the search behavior of Dutch-speaking nursing students with a nonnative knowledge of English who searched for information in MEDLINE/PubMed about a specific theme in nursing. We examine whether and to what extent their search efficiency is affected by their language skills. Our task-oriented approach focuses on three stages of the information retrieval process: need articulation, query formulation, and relevance judgment. The test participants completed a pretest questionnaire, which gave us information about their overall experience with the search system and their self-reported computer and language skills. The students were briefly introduced to the use of PubMed and MeSH (medical subject headings) before they conducted their keyword-driven subject search. We assessed the search results in terms of recall and precision, and also analyzed the search process. After the search task, a satisfaction survey and a language test were completed. We conclude that language skills have an impact on the search results. We hypothesize that language support might improve the efficiency of searches conducted by Dutch-speaking users of PubMed.

- Rez. in: JASIST 55(2004) no.7, S.651-652 (D.G. Smith): "A complex myriad of online information sources and services are currently accessible to knowledge workers worldwide. Those who have a computer equipped with a modern or Internet access can avail themselves of bibliographic, scientific, and full-text databases in a staggering number of disciplines. These online services, fueled by technological advancement, are in a constant state of change. Innovation occurs so quickly that it is difficult for knowledge workers to remember any other technological reality but the present. In such an environment, the origin of online information services often goes unconsidered. A History of Online Information Services, 1963-1976, by Charles P. Bourne and Trudi Bellardo Hahn, sheds light an the pioneering efforts of those who made current online information services possible. Michael Buckland states in the book's foreword that Bourne and Hahn's volume is the first history of the early online years. It covers the appearance of the first online information retrieval system in 1963 and concludes during 1976 when several commercial online information services, including DIALOG and LEXIS, became forerunners in the nascent online industry. Although developments in computing technology and communication networks were important to early online efforts, these topics are not discussed in the book. However, there are cases when offline computing technologies, such as database searching with punched cards, are reviewed if they are important to the development of online retrieval systems. ...
Overall, Bourne and Hahn's book is richly detailed and extensively documented. In the book's introduction, the authors provide a good overview of other online system histories, but they also write about a lack of archival and secondary sources in this area. This explains why it took the authors 15 years to gather information for this volume, most of it derived from technical reports, newsletters, and personal interviews. From a research standpoint, the authors have done an excellent job. However, while no one can take issue with the book's level of scholarship, the presentation of the research could have been more effective. The majority of the book is written in a straightforward, factual manner that is difficult to read as an historical narrative. Except for Chapter 10, there is very little writing in the book that engages the reader and captures the human side of the online information retrieval story. A quote from W. Boyd Rayward an the back of the book's dust cover calls the work "encyclopedic," and in many ways the book as it exists would have worked better as an encyclopedia. Even the book's layout, with double instead of single columns, hints at its reference-like qualities. To be fair, though, it is entirely possible that Bourse and Hahn may have wanted to create a book with a human interest angle, but the lack of documentation may have prevented them from creating such a work. In short, A History of Online Information Services, 1963-1976, does a commendable job of encapsulating the significant people, organizations, and events that helped shape early online information services. Given the problems Bourne and Hahn had in gathering historical evidence for their book, it makes one wonder about the implications for future historical work in the online field. One can only hope that organizations are archiving enough historical material to be able to write the post-1976 online story."

- Abstract
- Describes a WWW based system which allows users to view, search and post geographically indexed information of the Earth. 2 geographic browsers have been developed: a 2D map browser capable of continuous scroll and zoom of an arbitrarily large sheet and a 3D flight-simulator browser capable of continuous flight around the Earth. On the server side, a geographical and geometrical server has been developed which contains large databases of images, elevations, lines, points and polygons stored in tiles structured into hierarchical pyramids or quadtrees. A metadata server has also been developed which contains URL pointers and geographical coordinates of various WWW documents, geographical information and geometrical models

- Abstract
- The paper is based an the database "E-journals Library" ("Elektronische Zeitschriftenbibliothek" - EZB). http://www.bibliothek.uni-regensburg.de/ezeit/. This database was developed by the University Library of Regensburg to offer a user-friendly interface independent of publishers' websites (like ScienceDirect). The main criterion for the service is real usage, not descriptive cataloging. The system is a web-based service, a dedicated system, outside the traditional catalogue. What are the functions of such a dedicated system? If we want to bring users to our digital libraries we should ask what they want from such a library and which service we should offer. 1. Content: as much as possible and highly relevant content. 2. Tools to search and browse for the content wanted. Browsing in a digital library is comparable to browsing in a reading room. 3. The digital library should have a clear profile of content. If these criteria coincide, the usage can be high. In the case of EZB it will be 4,000,000 users this year. The service is growing steadily, corresponding to the increasing supply of electronic jounals and the increasing acceptance of digital publications. When I compare such a dedicated system with a reading room, I want to say: "There are different functions necessary compared to a collection of printed books. The EZB is not merely a catalogue; it has the functions of a virtual reading room, which are quite different from an OPAC. Another question is: what is necessary to present electronic journals? This material is different from monographs, which are normally highly specialized. The purpose of this paper is to show the different methods of access which are offered to the user and which methods are used most.

- Abstract
- The large number and variety of online databases in the field of environment sciences and chemistry underlies the need for a cooperative evaluation approach. Presents 2 evaluation criteria, divided into 4 headings; general criteria (size of data source, cost of 1 hour searching, updating of database, availability on other media); chemical relevant criteria (number of chemicals, identification parameters of chemicals, test set chemicals, development of chemicals), environmental relevant criteria (information parameters for chemicals, parameter development); and criteria describing environmental chemicals (use of chemicals, quality of database). A 6 number scoring system is applied to these criteria and the Hasse diagram technique is presented for 19 bibliographic online databases using these criteria. Using this technique, 'good' and 'bad' databases are identified and changes in the database content from 1995 to 1998 can be visualized

- Abstract
- Reviews the PowerSearch multifile searching software introduced by ORBIT Search Service as it is used for searching patent databases. Looks at its useful features: deduping, patent family grouping, merge, and virtual file merging. Looks at some possible improvements to both PowerSearch itself and to the ORBIT system to accomodate PowerSearch

- Abstract
- Describes an experiment using 48 sixth-grade students to compare retrieval techniques using the print and CD-ROM versions of Compton's Encyclopedia. Four queries of defferent complexity (measured by the numer of terms present) were searched by the students after a short training session. The searches were timed and the retrieval steps and search terms were noted. The searches were no faster on the CD-ROM than the print version, but in both cases time was related directly to the number of terms involved. The students coped well with the CD-ROM interface and its several retrieval paths
