- Abstract
- At Rotterdam Port Authority an information database has been created with approx. 100.000 full text documents online. Topic software has been used to identify word groups and refine search strategies to optimize precision and recall. The software guides users from selected terms to other relevant word combinations. Although the system would benefit from further refinement, users are generally satisfied. The database includes a number of foreign language documents but lacks a thesaurus of foreign terms

- Abstract
- At Limburg Provincial Central Library and Information Service in the Netherlands the online public catalogue has been replaced by a new system, Foundation. The OPAC network was an automated version of the card catalogue, whereas Foundation has been developed entirely from scratch. The system runs on Windows software and assists even inexperienced users to formulate suitable search strategies. The system accepts online catalogue records from other sources and has attracted considerable intersts from several areas, including the publishing industry

- Abstract
- In 1989 Brabant Catholic University was the first university in the Netherlands to provide an online campus information service. Since that date other universities in the Netherlands have inaugurated systems providing a wide range of information services, including access to the respective library's catalogues. Ease of use varies from system to system and there is an urgent need to standardize system commands. Libraries can provide useful help in creating such services. In return ther services provide a useful adjunct to the organization's library

- Abstract
- In the last 10 years a number of libraries in the Netherlands have developed akternative shelf arrangements to the standard SISO system. A survey undertaken at Felde children's library following the implementation of an alternative arrangement showed that children had been unaware of the change. In 1989 the Nederlands Bibliothekk en Lektuur Centrum (Dutch Centre for Libraries and Reading) began developing a system based on trials at 15 libraries. Further implementations of the system should take account of developments with automated catalogues

- Abstract
- Retrieval techniques may be based on the full text of documents, or on descriptors selected from a thesaurus. The latter approach constitutes an attempt to bridge the gap between demand and documents, which causes problems if demand cannot be forecast. Building up a thesaurus involves choosing the method of collecting descriptors, choosing the actual descriptors and making the system easily accessible to users. Classification and a classified catalogue are essential to the organisation of knowledge. Rules for the formation of classes have developed out of natural systems of classification. Chain indexing greatly aids the formation of the subject index. UDC and DDC are used in most documentation centres in the Netherlands. Public libraries mostly use SISO, a Dutch universal classification system

- Abstract
- The concept of a system combining information in both textual and pictorial format was first suggested by Vannevar Bush in 1945. The present hypermedia system was originally developed by Tim Berners Lee at CERN in 1989 and provides access to brief documents, which are interlinked and contain text, images, sound and video. The system has become widely available through the WWW, which enables users to 'navigate' through related information. Recent developments include the ability to view objects in virtual reality and the automatic generation of document links

- Abstract
- As a result of the growing pace of developments in the electronic information industry the EC Commission invited applications for the creation of a data base of producers and their services. Tha contract was awarded to the European Information Industry Association, which in collaboration with ECHO (European Commission Host Organisation) has created the I'M GUIDE (Information Market Guide) service. Information on the products, services and manufacturer is contributed by a network of correspondents. The data bank is updated fortnightly and contains more than 4.000 references. The system is available for online access 24 hours daily. It offers natural language searching in English, french and Italian and a menu-driven system in the 9 EC languages

- Abstract
- To assist users of the national SURFnet information network in the Netherlands Utrecht City Libraries have developed the Kermit user help package. The Gopher package developed by the University of Minnesota in the United States also enables users to navigate through the system. The Open Bibliotheek Network (Open Library Network) allows users both to access and request items from other library collections via SURFnet. The system thus enables enquirers to male optimum use of library resources in the Netherlands

- Abstract
- At Rotterdam Ports Authority in the Netherlands the Habour information database includes a press cuttings service and various online databases. To enable research staff to have direct access to information the POINT (Point Information Net) was begun in 1993. Using Verity software POINT provides simultaneously full text searching on a range of databases. The software uses current Web indexing technqiues to overcome the problems of excessive recall and low precision. A key element is the system's ability to recognise word combinations

- Abstract
- Developments in electronic communication technology have meda online databases a normal part of library collections. To provide users with direct access to Internet resources the Dutch Royal Library has cooperated with several university libraries in the Netherlands to develop the Nederlandse Basisclassificatie Web. Subject specialists select sources, add English summaries and NBW code, and input them to the online database. A Web desk and training workshops have been provided to assist users, and improvements to the system will simplify search procedures

- Abstract
- A study of new information systems and databases shows that insufficient help is provided to enable users to exploit these resources adequately. Despite surveys which show that users rarely employ Boolean logic appropriately in formulating search strategies database producers continue to use it as an indexing tool. Moreover, although much effort has been devoted to developing navigation techniques to search databases, problems still arise with insufficient entry points and links between systems. Resources are currently being channelled into the development of virtual reality systems to help users

- Abstract
- In the Netherlands the Gemeenschappelijke Onderwerps Ontsluiting (Standard Subject Indexing) schedules were developed for libraries using the national online catalogue. At Leiden University's Institute voor Oost-Europees Recht en Ruslandkunde use of both UDC and GOO schedules enabled a comparison to be made of the systems. A study of approx. 1.400 titles showed that GOO was more effective in retrieving relevant documents, whereas UDC was more suited for compiling subject bibliographies. The best of both schemes should be combined for optimal retrieval

- Abstract
- The library of the Prince Leopold Institute for Tropical Medicine in Antwerp, Belgium is a specialised research library with some 14.000 books and 550 current periodical subscirptions. Since 1990 the library has used Bib/SEARCH (version 2.9) library management program to provide online catalogue and database information facilities. The system is structured to enable easy transfer of data from other sources, and fields may be defined according to the library' needs. Despite minor problems such as the indexing routine, experience at the Institute has been positive. A new version of the system is currently under development

- Abstract
- To assist users with accessing the growing range of information sources Twente University Library in the Netherlands has developed OBIS (Online Bibliotheek Informatie Systeem / Online Library Information System). OBIS provides access to online databases and a range of library catalogues, including Twente's. However, a survey of staff in the Department of Applied Education and Information Science Studies showed that library services were underused. The survey showed that users relied heavily on printed information and contacts with colleagues. To overcome this a user education programme is currently being developed

- Abstract
- Modern online information systems have been criticized as being too complicated for the average information seeker. To overcome this problem interfaces have been developed to assist users at all stages of the information transfer process from searching to analysis and evaluation of retrieval data. However, the effectiveness of an interface will depend on the skills of the user. Further development of interfaces will be aided by the use of Windows and mouse controlled systems

- Abstract
- A recent survey at the Royal Library in the Netherlands showed that subject headings are more efficient than title keywords for retrieval purposes. 475 Dutch publications were selected at random and assigned subject headings. The study showed that subject headings provided additional useful information in 56% of titles. Subsequent searching of the library's online catalogue showed that 88% of titles were retrieved via subject headings against 57% through title keywords. Further precision may be achieved with the help of indexing staff, but at considerable cost
