  Ercegovac, Z.: Minimal level cataloging : what does it mean for maps in the contexts of card catalogs, online catalogs, and digital libraries?.
  In: Journal of the American Society for Information Science. 49(1998) no.8, S.706-719.
  
  Abstract: In this article, we examine some of the proposals which have dealt with the problems in cataloging in 2 different technological contexts: printed-card catalogs and online catalogs. We first look at some of the measures which attempted to deal with the 'crisis in cataloging' at the Library of Congress in the 1940s. Then we address some of the current problems in cataloging in the era of OPACs. In particular, we discuss the extent to which minimal-level cataloging, as defines by AACR and implemented in the OCLC database, works for maps. Our discussion is organized around 2 main groups of access points: controlled vocabulary data elements, including name data elements, and free-text data elements. In closing, we discuss prospects that the next generation of online catalogs uisng the Z39.50 protocol and SGML format might offer to minimal-level cataloging for maps

  London : British Library, 1998. 91 S.
  (British Library research and innovation report; 103)
  
  Abstract: Describes work of the BOPAC2 project, funded by the British Library Research and Inoovation Centre, from Sep 1996 to Jan 1997, to investigate the issues involved in managing large and complex retrievals involving Z39.50 searches, including searches of multiple databases. The system is a WWW front end that allows simultaneously access to a number of library OPACs via Z39.50. The system is designed to make access to large and complex retrieval simpler, similar records are clustered together and retrievals may be sorted in a number of ways and by different criteria. Describes the design, development and evaluation of the system with suggestions for future work

  Oddos, J.-P.: ¬Un catalogue sur Internet, pour quoi faire?.
  In: Bulletin d'informations de l'Association des Bibliothecaires Francais. 1998, no.178, S.7-13.
  
  Abstract: Since Sep 1997 the catalogue of the French National Museum of Modern Art's documentation collection has been on the Internet. The original intention was to expand its function as a local collection management tool, and provide a worldwide reference source, using Z39.50. The process highlighted the catalogue's imperfection (local variations, exploded records). Future developments include an English version, refinement of the home pages and an updating programme. So far the impact is unclear, but this should eventually provide a basis for international cooperation

  Turner, F.: Selecting a Z39.50 client or Web gateway.
  In: Library hi tech. 16(1998) no.2, S.7-18.
  
  Abstract: Presents a range of evaluation criteria in the selection of a Z39.50 client and poses questions that should be asked when reviewing and testing end user products. The areas for consideration include whether to buy or build a Z39.50 client, the end user's requirements, connecting to a remote server, searching, managing the search response, Z39.50 services, the vendor, and testing. As some knowledge of the Z39.50 standard is helpful in the selection process and contributes to an understanding of how a Z39.50 client works, brief descriptions of some of the major aspects of Z39.50 are included

  Skogmar, G.: Z39.50 i praktiken.
  In: DF Revy. 21(1998) no.5, S.128-130.
  
  Abstract: Z39.50 is a standard protocal for database searching. LIBRIS, BIBSYS and DANBIB use Z39.50 servers and many suppliers of local library systems have Z39.50 functions in their online catalogues. Lists the protocol's advantages for librarians and its most important functions. Version 3 was adopted in 1995 and contains many new functions and attribute sets. When attribute sets are used, profiles are necessary. Most Nordic profiles are based in the ONE profile, while the European national libraries use the CENL profile. The ILL protocol is used in preference to Z39.50's Item Order function for interlending. the simplest way of searching with Z39.50 is probably with a WWW gateway. Its greatest potential is as a protocol for searching in databases from libraries, museums, archives and othe cultural institutions

  EU transcends library limits.
  In: Information world review. 1997, no.122, S.2.
  
  Abstract: ZNavigator, a search engine allowing information professionals to access every public library catalogue compliant with Z39.50, has been posted for free use on the WWW. The interface has been designed by Spanish software company EnWare SA in cooperation with South Bank University London, the University of Florence and the University of Alcala de Henares, Madrid. ZNavigator provides access to both bibliographic and full-text catalogues. Catalogues can be grouped into subject areas, and selected databases are then displayed in separate windows. Around 300 library catalogues may be accessed including national libraries; union catalogues; some university library catalogs; serials agent's databases, CD-ROM databases and large publisher's databases

  Provansal, A.: Neuf mois après.
  In: Bulletin d'informations de l'Association des Bibliothecaires Francais. 1997, no.174, S.155-157.
  
  Abstract: Electronic documents are creating new services and generating new demands, with consequent impacts on the means of transmitting knowledge, international standards and democratisation of access. Universal bibliographic control depends on common rules for bibliographic description and format to ensure compatibility and exchange. In addition to ISBN and UNIMARC for cataloguing, Z39.50 allows searching of heterogeneous databases and SGML makes cataloguing in publication a reality. Such developments must be based on knowledge of what users want and their real search and consultation practices, not what the system devisers have the technology to create

  Lahary, D.: ¬Le jeu de puzzle de l'acces aux catalogues : World Wide Web et/ou Z39.50.
  In: Bulletin d'informations de l'Association des Bibliothecaires Francais. 1997, no.174, S.82-85.
  
  Abstract: To access a remote catalogue the searcher can use the Z39.50 standard as interface, which requires appropriate software; or for databases accessible on the WWW use a common gateway interface. The multibase access advantage of Z39.50 can also be obtained through a Web navigator by inserting a Web server/Z39.50 client software connector: this can be located either on the search site, in an intermediary position or on the database site, so determining the range of databases which can be searched. Z39.50 also offers interesting possibilities for joint and local cataloguing: multibase searching can equally be realised on intranets

  Yeates, R.: Managing access to the digital library : the CaseLibrary project.
  In: Electronic library and visual information research: Proceedings of the 4th ELVIRA Conference (ELVIRA 4), Electronic Library and Visual Information Research, De Montfort University, Milton Keynes, May 1997. Ed. by C. Davies u. A. Ramsden. London : Aslib, 1997. S.207-218.
  
  Abstract: Describes the development of new library management software as a cooperative project between the South Bank University, London, the universities of Florence and Alcala de Henares, and a Spansih software developer, EnWare SA, with funding from the European Third Framework Libraries Programme. The main requirement was to work on software which would run on most kinds of intelligent terminals, including PCs, Macintosh and UNIX machines, and which would allow users to search a variety of target resources, such as the library OPAC and CD-ROM titles. As most suppliers were in the process of developing their own Z39.50 server capabilities, it was decided to make use of these rather than develop new interfaces. The emergence of Web software as low cost, flexible clients led the CaseLibrary project team to shift the emphasis of their work from the creation of a full user client to the overall management and control system for electronic information resources. Discusses the system users, and the system architecture and components, such as TaskManager, ZNavigator, Administration client, and the CaseLibrary Access Control Token Server (CACTUS)

  Hinnebusch, M.: Z39.50 at ten years : how stands the standard?.
  In: Journal of academic librarianship. 23(1997) no.3, S.217-221.
  
  Abstract: The ANSI Z39.50 standard was adopted 10 years ago. It outlines a set of rules and procedures to allow a computer system to search the databases provided by another system and to retrieve the results of that search. Traces its development adoption in library automation product lines. Recent major developments have been the migration to version 3 and the adoption of community profiles. Community profiles are documents that describe agreements that a community of interest develops to ensure clients and servers can interpret in specific ways. Describes the Government Information Locators Service, WAIS, ATS, ZDSR, Cataloguing, CEOS CIP, Digital Collection, Digital Library Objects and Museum Profiles

  Lynch, C.A.: Building the infrastructure of resource sharing : union catalogs, distributed search, and cross database linkage.
  In: Library trends. 45(1997) no.3, S.448-461.
  
  Abstract: Effective resourcesharing presupposes an infrastructure which permits users to locate materials of interest in both print and electronic formats. 2 approaches for providing this are union catalogues and Z39.50 based distributed search systems and computer to computer information retrieval protocols. The advantages and limitations of each approach are considered, paying particular attention to a relaistic assessment of Z39.50 implementations. Argues that the union catalogue is far from obsolete and the 2 approaches should be considered complementary rather than competitive. Technologies to create links between the bibliographic apparatus of catalogues and abstracting and indexing databases and primary content in electronic form, such as the new Serial Item and Contribution Identifier (SICI) standard are also discussed as key elements in the infrastructure to support resource sharing

  Combs, J.: Znavigator.
  In: Library software review. 16(1997) no.4, S.247-260.
  
  Abstract: The Z39.50 standard was developed to combat information smog - the ever growing trivial data surrounding vital information - by minimizing the need for network operators to regularly learn new interfaces. Znavigator is a Z39.50 client which conforms to nearly all ANSI/NISO Z39.50 specifications, incorporating the BIB-1 attribute set. Presents a digest of these attributes and the vendor, hardware and operating details for Znavigator. Anyone using Znavigator with servers on the Internet should be quite satisfied with the results
