The serial coverage and indexing policies of Aquatic Sciences and Fisheries Abstracts (ASFA), Oceanic Abstracts, Biosis, and Georef were compared. Analyses indicated considerable overlap in serial sources in marine biology for ASFA, Oceanic Abstracts, and Georef. Biosis appeared to include the largest amount of material relevant to marine biology and Georef the largest relevant to marine geology. Oceanic Abstracts and Georef provided the most extensive general subject indexing, Biosis the most complete taxonomic indexing, and ASFA and Georef the easiest systems for geographic retrieval.

An empirical investigation of the consistency of retrieval through Internet search engines is reported. Thirteen engines are evaluated: AltaVista, EuroFerret, Excite, HotBot, InfoSeek, Lycos, MSN, NorthernLight, Snap, WebCrawler and three national Dutch engines: Ilse, Search.nl and Vindex. The focus is on a characteristics related to size: the degree of consistency to which an engine retrieves documents. Does an engine always present the same relevant documents that are, or were, available in its databases? We observed and identified three types of fluctuations in the result sets of several kinds of searches, many of them significant. These should be taken into account by users who apply an Internet search engine, for instance to retrieve as many relevant documents as possible, or to retrieve a document that was already found in a previous search, or to perform scientometric/bibliometric measurements. The fluctuations should also be considered as a complication of other research on the behaviour and performance of Internet search engines. In conclusion: in view of the increasing importance of the Internet as a publication/communication medium, the fluctuations in the result sets of Internet search engines can no longer be neglected.

The assignment of targets to instruments in developing countries cannot satisfactorily follow any simple universal rule. Which approach is appropriate is influenced by whether the economy is dominated by primary exports, by the importance of the domestic bond market and bank credit, by the extent of existing restriction in foreign exchange and financial markets, by the presence or absence of persistent high inflation, and by the existence or non‐existence of an active international market in the country's currency. Eighteen observations and maxims on stabilisation policy are tentatively drawn (pp. 64–8) from the material reviewed, and the maxims are partly summarised (pp. 69–71) in a schematic assignment, with variations, of targets to instruments.

In response to its mission of identifying and describing problems of interdisciplinary searching, and of proposing remedies and solutions, the ICSTI Group on Interdisciplinary Searching gathered the relevant information through a questionnaire addressed to the database builders, online system vendors, search intermediaries and end users; analysed and organised the input; and presented a report. The report discusses the problems within six distinct categories: coverage and technical content of the database; bibliographic information; textual content; numeric data; file organisation, and interdisciplinary searching on multiple hosts. Under each category, problems are first listed in a generic way and then described in greater detail. Numerous specific examples are given with explanations, whenever feasible, of the reasons for their occurrence. For each category, possible remedies and solutions are listed. The most essential recommendations that have emerged deal with the need for greater standardisation at every stage in building the databases and in organising access to them. A number of bodies and groups working on international and national standards, and on solving other specific aspects of the problems, have been identified. The needs for close co‐operation, exchange of good documentation, extensive training and mutual understanding are most evident.

A method of systematically assessing the “first-round” impact of tax and transfer policy changes on the income distribution and the incidence of relative income poverty is proposed. It involves the construction of a “distributionally neutral” policy, which can be approximated by a policy that indexes tax allowances, credits and bands and welfare payment rates in line with a broad measure of income growth. The impact of actual policy changes in five EU countries over the 1998–2001 period is then measured against this benchmark, using the EUROMOD tax-benefit model.

Organisations responsible for the maintenance of photographic archives are showing a developing interest in the creation of compact disc digital catalogues. These are perceived as a means of providing a ‘shop window’ to their collections, and a facility whereby their clients can order pictures directly without recourse to request mediation by a picture researcher or librarian. The Hulton Deutsch Collection's pioneering approach to this new dimension in picture library operation is described, with particular reference to those policies on indexing and interface design by which that approach was guided. Brief consideration is given to the extension of such desktop browsing facilities into the arena of high‐resolution electronic image delivery.

At the beginning of the 1970s it became apparent to the Ministry of Agriculture, Fisheries and Food that the use of computers for information work merited serious consideration. We had taken part in investigations which indicated that the technology was well developed and reliable. We knew that large scale commercial services were available. What we did not know was the real value of these external services to the Ministry. All the databases concerned were derived from very familiar printed secondary journals. Did mechanized operation offer substantial advantages? Was the cost justified? How could mechanized operations fit into the present library activities? If the use of computers did offer improved facilities, what administrative arrangements were necessary? It was decided, therefore, to attempt to answer these questions by the evaluation of external computer‐based bibliographic information services under practical conditions.

Complete texts of many journals are now available for online searching. Most of these full text databases have been made available on the same or similar search systems that provide access to bibliographic information. The systems use inverted files that retain limited context information (e.g., paragraphs and location of words within paragraphs). The retrieval techniques used are simply those that were developed earlier for bibliographic databases. Retrieval relies on Boolean logic, word stem searching with truncation, and word proximity specification. Minor adjustments have been made for the display of full text databases, allowing words resulting in retrieval to be displayed in context; but changes have not been made in retrieval techniques. This is due to the reliance on search systems that provide access to many types of databases, all of which are by‐products of improved techniques for creating printed publications.

The purpose of this paper is to highlight the problems of using metadata to file electronic documents as well as the problems of using a purely functional filing scheme. It aims to explore how a functional file plan can be created from a business classification scheme by inserting “metadata signpost folders” at strategic points in the filing hierarchy to create a “hybrid functional file plan”.

The paper draws on experience and published literature to discuss methods for creating a hybrid functional file plan.

The paper concludes that functional filing is the only method of filing e‐documents that can effectively support good information management practice, enabling all e‐documents to be managed in line with corporate information management policies, and that it may also be the only viable method of providing true “shared” filing in support of knowledge management and business efficiency.

The article shows that a functional filing scheme, retrieving, cross‐referencing and grouping documents by subject (or other metadata attributes) requires special measures and suggests that current IT, EDRM and related technologies may not fully meet the requirements by searching/sorting on metadata terms. It may be necessary to compromise a purely functional file plan by the inclusion of metadata “signpost” folders into the functional folder structure in order to create a hybrid functional file plan.

To construct an index (index of environmental sensitivity performance) to be used in a cross‐country trade model in order to analyze the effect of various degrees of environmental stringency on the trade patterns, and especially on the export performance of the countries.

The gravity model of trade is used in order to find the effects of environmental stringency on the variation in trade flows.

The study shows that environmental stringency has an important impact on the export of the countries. The impact of the degree of environmental stringency on the exports is significantly negative suggesting an inverse relationship between export values and relative environmental sensitivity performance of the nations.

This study supports the argument that the environmental stringency level differential between developing and developed nations is a crucial criteria in terms of explaining shifts in the trade patterns and international specialization of the countries.
