    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
    Since their inception in the early 1960s the strength and unique aspect of the ISI citation indexes has been their ability to illustrate the conceptual relationships between scholarly documents. When authors create reference lists for their papers, they make explicit links between their own, current work and the prior work of others. The exact nature of these links may not be expressed in the references themselves, and the motivation behind them may vary (this has been the subject of much discussion over the years), but the links embodied in references do exist. Over the past 30+ years, technology has allowed ISI to make the presentation of citation searching increasingly accessible to users of our products. Citation searching and link tracking moved from being rather cumbersome in print, to being direct and efficient (albeit non-intuitive) online, to being somewhat more user-friendly in CD format. But it is the confluence of the hypertext link and development of Web browsers that has enabled us to present to users a new form of citation product -- the Web of Science -- that is intuitive and makes citation indexing conceptually accessible. A cited reference search begins with a known, important (or at least relevant) document used as the search term. The search allows one to identify subsequent articles that have cited that document. This feature adds the dimension of prospective searching to the usual retrospective searching that all bibliographic indexes provide. Citation indexing is a prime example of a concept before its time - important enough to be used in the meantime by those sufficiently motivated, but just waiting for the right technology to come along to expand its use. While it was possible to follow citation links in earlier citation index formats, this required a level of effort on the part of users that was often just too much to ask of the casual user. In the citation indexes as presented in the Web of Science, the relationship between citing and cited documents is evident to users, and a click of the mouse is all it takes to follow a citation link. Citation connections are established between the published papers being indexed from the 8,000+ journals ISI covers and the items their reference lists contain during the data capture process. It is the standardized capture of each of the references included with these documents that enables us to provide the citation searching feature in all the citation index formats, as well as both internal and external links in the Web of Science.

    Abstract
    All types of information can be referenced to a geographic place. Maps, aerial photographs, and remote sensing images are spatially georeferenced. Other forms of information such as books, articles, research papers, pieces of music, and art are often linked to a geographic location through place names (geographic names). A gazetteer (a dictionary of geographic names) that is spatially referenced itself provides the bridge between these two types of georeferencing. With a georeferenced gazetteer translation service, a user can start with a geographic name and find information that is described with either geographic names or with geospatial coordinates. Use of this powerful indirect geospatially referencing tool can be applied as a common approach to libraries, bibliographic files, data centers, web resources, and museum and specimen collections and can be particular useful across language barriers since latitude and longitude coordinates are universally understood. The Alexandria Digital Library has implemented a gazetteer component for its georeferenced digital library. This experience resulted in the creation of a Gazetteer Content Standard, a Feature Type Thesaurus, and an operational interactive gazetteer service. This paper describes the development of these components and illustrates the use of this tool in a georeferenced digital library. It also relates progress in working with Federal agencies and others toward developing shareable gazetteer data through Digital Gazetteer Information Exchange programs

    Abstract
    Presents a brief, critical review of LISA PLaus: the CD-ROM database version of LISA and which includes the database of Current Research in Library and Information Science (CRLIS). The review covers the DOS version only, as it appeared in the Summer 1996 CD-ROM, noting that the Windows version was planned for the future. Points to the way LISA has found its mark, if not its fortune, in LISA Plus and notes its strengths, including: ideal suitability for current awareness in library and information science (LIS); massive and convenient consolidation of the published LIS literature; and massive increase in coverage from 7.900 abstracts in 1993 to over 12.000 currently. Criticizes certain features of LISA Plus, notably: the OPTI-Ware search interface; the combination of 2 databases (LISA and CRLIS) in a single, searchable database; and certain unexpected effects caused by the building of the Subject and Free Text indexes. Points particularly to great lack of consistency in the indexes and the indexing (faults that were fully rectified by a complete overhaul of the data in Summer 1996). Notes that LISA Plus is the first port of call for both information researchers and information science students. The Windows version of LISA Plus was launched in Spring 1997

    Abstract
    Highlights some of the differences between printed and electronic materials; problems of preservation of initial texts, inaccessible formats, problems over the control of access and costs of electronic media. Libraries need to tackle issues that can ensure that their clients will have as unconstrained access to electronic information as they now have to printed information, and that electronic texts that are worth preserving are maintained

    Content
    Volume 1 is divided into three parts. Part One (Chapters 1 and 2) constitutes an introduction to the reference process and automated reference services. Part Two, "Information: Control and Access," consists of Chapters 3 through 6 and covers an introduction to bibliographies, indexing, and abstracting services. Chapters 7 through 12 are in Part Three, "Sources of Information," which include encyclopedias, various ready reference sources, biographical sources, dictionaries, geographical sources, and government documents. It is as pointless for students to memorize details about specific reference sources, as it is necessary for them to grasp the essential areas of agreement and difference among the various forms. To this end, every effort is made to compare rather than to detail. Only basic or foundation reference works are discussed in this volume. But readers may not find all basic titles included or annotated because: (1) There is no consensus an what constitutes "basic". (2) The objective of this text is to discuss various forms, and the titles used for that purpose are those that best illustrate those forms. (3) The annotations for a specific title are duplicated over and over again in Guide to Reference Books and Guide to Reference Materials, which list the numerous subject bibliographies. In both volumes, suggested readings are found in the footnotes and at the end of each chapter. When a publication is cited in a footnote, the reference is rarely duplicated in the "Suggested Reading." For the most part, these readings are limited to publications issued since 1987. In addition to providing readers with current thinking, these more recent citations have the added bonus of making it easier for the student to locate the readings. A number of the suggested reading items will be found in Reference and Information Sources, A Reader, 4th ed., published by Scarecrow Press, in 1991. It is beyond argument, of course, that all readings need not necessarily be current and that many older articles and books are as valuable today as they were when first published. Thanks to many teachers' having retained earlier editions of this text and the aforementioned Scarecrow title, it is possible to have a bibliography of previous readings. As has been done in all previous editions, the sixth edition notes prices for most of the major basic titles. This practice seems particularly useful today, since librarians must more and more be aware of budgetary constraints when selecting reference titles. CD-ROMS are listed where available. Prices are based an information either from the publisher of the original reference source or from the publisher of the CD-ROM disc. If a particular work is available online, the gross hourly rate as charged by DIALOG is given for its use. Both this rate and the book prices are current as of late 1990 and are useful in determining relative costs. Bibliographic data are based an publisher's catalogs, Books in print, and examination of the titles. The information is applicable as of late 1990 and, like prices, is subject to change.

    Abstract
    Reviews the exponential growth of Internet resources leading to the emergence of hundreds of Internet directories to organize those resources. Based upon their format, content, and characteristics, these Internet directories are categorized into 8 groups. From one of these groups. 'Subject directories published in professional journals' all published Internet directories are identified and listed in detail. Using Paradox-For-Windows, a comprehensive database of more than 350 of these directories was developed. Analyzes and interprets the data contained in the database and reviews the strengths and weaknesses of print Internet subject directories as compared to online directories and other search engines

    Abstract
    CD-ROMs generate increased questions that require individual instruction, staff training and bibliographic instruction. Many libraries are moving away from CD-ROMs towards locally mounted databases and access to remote databases, but the variety and sheer number of CD-ROMs may guarantee their survival, especially in larger university libraries or special libraries. With increasing services and collections offered, quality reference service may decay. Discusses undergraduates and the learning process and improvements to service instruction and the reference service
