A study comparing centralized CD-ROM and decentralized intranet access to MEDLINE

Objective: The purpose of this study was to evaluate the efficacy of a decentralized intranet access in each medical department as opposed to centralized unique MEDLINE access in the medical library.

Compilation of results of the STRATAGEM project as ISO-image of the final CD-ROM

The study of the Neogene (Miocene to Holocene) stratigraphic record on the glaciated Atlantic margin of NW Europe has, to date, largely been undertaken on an ad-hoc basis. Whereas a systematic approach to understanding the stratigraphic development of Palaeogene and older strata has been undertaken in areas such as the North Sea, West of Shetland and Norway, the problem of establishing a Neogene framework has been only partly addressed by academia and the oil industry. In most cases where a Neogene stratigraphy has been constructed, this has been largely in response to problem solving and risk assessment in a restricted area. Nevertheless, in the past few years it has become increasingly apparent that there is a common history in the Neogene development of the passive Atlantic margin of NW Europe, between mid-Norway and SW Ireland. The inspection and interpretation of an extensive geophysical and geological database has identified several regionally significant and correlatable unconformities along this continental margin. Thus, a regional approach to the stratigraphical development of the Neogene succession on the glaciated European Atlantic margin is undertaken in this volume.

R-ArcticNet, A Regional Hydrographic Data Network for the Pan-Arctic Region (ISO-image of CD-ROM)

We describe the contemporary hydrography of the pan-Arctic land area draining into the Arctic Ocean, northern Bering Sea, and Hudson Bay on the basis of observational records of river discharge and computed runoff. The Regional Arctic Hydrographic Network data set, R-ArcticNET, is presented, which is based on 3754 recording stations drawn from Russian, Canadian, European, and U.S. archives. R-ArcticNET represents the single largest data compendium of observed discharge in the Arctic. Approximately 73% of the nonglaciated area of the pan-Arctic is monitored by at least one river discharge gage giving a mean gage density of 168 gages per 106 km2. Average annual runoff is 212 mm yr?1 with approximately 60% of the river discharge occurring from April to July. Gridded runoff surfaces are generated for the gaged portion of the pan-Arctic region to investigate global change signals. Siberia and Alaska showed increases in winter runoff during the 1980s relative to the 1960s and 1970s during annual and seasonal periods. These changes are consistent with observations of change in the climatology of the region. Western Canada experienced decreased spring and summer runoff.

CD-ROM Acrobat Journals Using Networks

The available technologies for publishing journals electronically are surveyed. They range from abstract representations, such as SGML, concerned largely with the structure of the document, to formats such as PostScript which faithfully model the layout and the appearance. The issues are discussed in the context of choosing a format for electronically publishing the journal: Electronic Publishing -- Origination, Dissemination and Design. PostScript is neither widely enough available nor standardised enough to be suitable; a bitmapped pages approach suffers from being resolution-dependent in terms of the visual quality achievable. Reasons are put forward for the final choice of Adobe s new PDF document standard for creating electronic versions of the journal.

Cd-Rom y el Acceso a la Información

Los avances científicos y tecnológicos en el mundo y su aplicación en las diferentes áreas del conocimiento han desarrollado una nueva era electrónica.Las computadoras y las telecomunicaciones han originado un nuevo escenario para las bibliotecas y centros de información que conduce a nuevos cambios en el uso de sus colecciones y en el incremento de sus servicios. Las bibliotecas y centros de información deben enfrentar estos cambios porque los usuarios demandan el acceso a la información en forma rápida y eficiente.El CD-ROM es una nueva tecnología que ha estado incursionando en las bibliotecas de manera muy efectiva. CD-ROM es una forma sofisticado de permitir el acceso a la información en cualquier campo; leyes, medicina, educación, agricultura, finanzas, ingeniería, etc
