Abstract

Funding from the UK Electronic Libraries (eLib) programme and the European Community's Fourth Framework programme assisted the initial emergence of information gateways (e.g., SOSIG, EEVL, OMNI in the UK, and EELS in Sweden). Other gateways have been developed by initiatives co-ordinated by national libraries (such as DutchESS in the Netherlands, and AVEL and EdNA in Australia) and by universities and research funding bodies (e.g., GEM in the US, the Finnish Virtual Library, and the German SSG-FI services). An account of the emergence of subject gateways since the mid-1990s by Dempsey gives an historical perspective -- informed by UK experience in particular -- and also considers the future development of subject gateways in relation to other services. When considering the development and future of gateways, it would be helpful to have a clear definition of the service offered by a so-called 'subject gateway'. Precise definitions of 'information gateways', 'subject gateways' and 'quality controlled subject gateways' have been debated elsewhere. Koch has reviewed definitions and suggested typologies that are useful, not least in showing the differences that exist between broadly similar services. Working definitions that we will use in this article are that a subject gateway provides a search service to high quality Web resources selected from a particular subject area, whereas information gateways have a wider criteria for selection of resources, e.g., a national approach. Inevitably in a rapidly changing international environment different people perceive different emphases in attempts to label services, the significant issue is that users, developers and designers can recognise and benefit from commonalties in approach.

The consequences of this are plain to see; the rural poor flock to cities, to shanty towns, driven by hope. And then often, finding that the Instagram nirvana is not available there, they seek it overseas, joining the ever greater numbers of economic migrants in search of a better life. These migrants in turn place new demands on the infrastructures and economies of the countries in which they arrive, undermining tolerance and further fuelling political populism. For me, the really concerning aspect of this, is that now, more than at any time in our history, our species needs to work together. We face awesome environmental challenges. Climate change, food production, overpopulation, the decimation of other species, epidemic disease, acidification of the oceans. Together, they are a reminder that we are at the most dangerous moment in the development of humanity. We now have the technology to destroy the planet on which we live, but have not yet developed the ability to escape it. Perhaps in a few hundred years, we will have established human colonies amidst the stars, but right now we only have one planet, and we need to work together to protect it. To do that, we need to break down not build up barriers within and between nations. If we are to stand a chance of doing that, the world's leaders need to acknowledge that they have failed and are failing the many. With resources increasingly concentrated in the hands of a few, we are going to have to learn to share far more than at present. With not only jobs but entire industries disappearing, we must help people to re-train for a new world and support them financially while they do so. If communities and economies cannot cope with current levels of migration, we must do more to encourage global development, as that is the only way that the migratory millions will be persuaded to seek their future at home. We can do this, I am an enormous optimist for my species, but it will require the elites, from London to Harvard, from Cambridge to Hollywood, to learn the lessons of the past month. To learn above all a measure of humility."

Victoria Frâncu, in her article "UDC-based thesauri and multiple access to information" compares the performance to two UDC structures in retrieval from an experimental database. Also related to UDC and retrieval is the article by Woulter Schallier "What a subject search interface can do." In this research, carried out at the K.U. Leuven University Library in Belgium, an experimental interface was developed for subject searching by UDC in an OPAC. The user searches by subject terms and obtains retrieval in which he/she can browse the terms displayed in a hierarchy of terms. Two of the papers are in languages other than English. "Summary of the activities of VINITI in the field of UDC," by Professor Y Arskiy is in Russian and "AENOR y la offerta de productos CDU," by Ana López is in Spanish. The latter describes several products of AENOR which are supportive of the application of the Spanish version of UDC. An article by Barbara Holder of the Forintek Canada Corporation, discusses "Updating the Global Forest Decimal Classification (GFDC)." This system is described as a sister classification to UDC designed to handle materials an forestry-related information resources. It can be used in conjunction with UDC to provide for non-forestry related materials. In addition there is a bibliography of UDC publications for the year prepared by Aida Slavic, who has also prepared a paper entitled "UDC translations: A 2004 survey report and bibliography" This discussion paper, accompanied by a table summarizes data an 38 translations, all but seven of which were published since the last survey of UDC translations carried out in 1982. Her article updates the previous work and brings together important information about the history and development of the various versions of UDC.
