Generally, Science and Technology information still falls under the category of "subscribed to" information. This is largely a result of the fact that most of the available literature in each field is compiled and presented by academians and members of the scientific community in refereed, professional and commercial publications. This means that much Science and Technology information belongs to the publishing community, those sources that are accessed through subscriptions (individual, corporate, academic and institutional) and located on publisher's Web sites. At present, very few publishers offer this information free of charge.

The year 2001 has seen a slight shift in the opinion of the scientific community at large that could signal a change in current publication policy. Many researchers and scientists want access to the materials of their peers. They feel that scientific research and discoveries should be freely shared. They want that information on their desktops. They want the information now. This view, while not all pervasive in the scientific community, has led to the establishment of several, freely accessible, peer-reviewed journals on the Web.

This movement toward open access to the literature of the scientific community is in its infancy. The numbers and kinds of materials available without charge to the general public are still limited, although many are excellent resources. A sampling is presented below for research use.

News Sources

Artigen Science News
http://www.artigen.com/newswire/scitech.html
An online news feed of articles in science from around the world updated hourly, with archives. Type a specific question, phrase or Name and search. This site also carries news feeds dealing with the following subject areas: the World, Health, Computers, and "Cool sites."

Issues in Science and Technology Online
http://www.nap.edu/issues/index.html
From the National Academy of Science, the National Academy of Engineering, and the U Texas at Dallas. The site has been available since fall of 1996. Access to content on the site does not require registration; access is free. Article types to search and retrieve materials from include articles, perspectives, reviews, roundtables; one can also search by author or title.

"Issues in Science & Technology is a forum for discussion of public policy related to science, engineering, and medicine. This includes policy for science (how we nurture the health of the research enterprise) and science for policy (how we use knowledge more effectively to achieve social goals), with emphasis on the latter.

Although Issues is published by the scientific and technical communities, it is not just a platform for these communities to present their views to Congress and the public. Rather, it is a place where researchers, government officials, business leaders, and others with a stake in public policy can share ideas and offer specific suggestions.

Unlike a popular magazine, in which journalists report on the work of experts, or a professional journal, in which experts communicate with colleagues, Issues offers authorities an opportunity to share their insights directly with a broad audience. And the expertise of the boardroom, the statehouse, and the federal agency is as important as that of the laboratory and the university. The ultimate purpose of Issues is admittedly idealistic but vital: to improve the effectiveness of public and private policy in making a better world and to raise the level of debate and mutual respect among all those who appreciate the critical contributions of science and technology."

Organizations

American Association for the Advancement of Science (AAAS)
http://www.aaas.org/
The American Association for the Advancement of Science (AAAS, pronounced "Triple-A-S") is the world's largest general science organization and publisher of the peer-reviewed journal Science [http://www.scienceonline.org/]. With more than 138,000 members and 275 affiliated societies, AAAS serves as an authoritative source for information on the latest developments in science and bridges gaps among scientists, policy-makers and the public to advance science and science education.

Founded in Philadelphia in 1848, AAAS is among the oldest societies in America. Many of today's most prestigious and influential scientific societies have their historical origins in AAAS. The site includes an online tour of the exhibit created to celebrate AAAS sesquicentennial (150th birthday), with links to each of the four time periods covered; a Science and Society section with access to information on the federal R & D budget; a Science Education section with information about education programs and science literacy for the future; a section on Science Careers including fellowships, internships, job listings and career fairs; and a hyperlink to the Science Online Web site, home of Science Magazine. Selected articles from Science are available for viewing.

American Society for Information Science and Technology (ASIST)
http://www.asis.org/
ASIST has been the society for information professionals leading the search for new and better theories, techniques, and technologies to improve access to information.

ASIST counts among its membership some 4,000 information specialists from such fields as computer science, linguistics, management, librarianship, engineering, law, medicine, chemistry, and education; individuals who share a common interest in improving the ways society stores, retrieves, analyzes, manages, archives and disseminates information, coming together for mutual benefit. ASIST bridges the gaps between disciplines, as well as between the research that drives and the practices that sustain new developments.

The National Academies
http://www.nas.edu/
The National Academies consist of four organizations: the National Academy of Sciences, the National Academy of Engineering, the Institute of Medicine, and the National Research Council. The National Academy of Sciences was created in 1863 by a congressional charter approved by President Abraham Lincoln. Under this charter, the National Research Council was established in 1916, the National Academy of Engineering in 1964, and the Institute of Medicine in 1970.

The National Academy of Sciences was created by the federal government to be an adviser on scientific and technological matters. However, the Academy and its associated organizations are private, not governmental, organizations and do not receive direct federal appropriations for their work. Studies undertaken for the government by the National Academies usually are funded out of appropriations made available to federal agencies. The great majority of the studies carried out by the National Academies are at the request of government agencies.

The subject index includes but is not limited to agriculture, behavioral and social sciences, biology, chemistry, computers, engineering, environmental issues, mathematics and physics, space and transportation, plus an extensive glossary of acronyms and terms used internally. In addition to a listing and descriptions of current projects and publications, the site includes its own Webcast, "Live! Listen to the Webcast." [http://video.nationalacademies.org/ramgen/encoder/061901.rm]. This requires the RealPlayer plugin and supplies the download link.

National Research Council
http://www.nas.edu/nrc/
To "associate the broad community of science and technology with the Academy's (National Academy of Sciences) purposes of further knowledge and advising the federal government." The publications link [http://www.nationalacademies.org/publications/] provides online access to books, periodicals and reports, many available for free online reading, all with purchase information.

Smithsonian Institute
http://www.si.edu
The Smithsonian Institute is composed of sixteen museums and galleries and the National Zoo and numerous research facilities in the United States and abroad. Research facilities include the Conservation and Research Center, the Smithsonian Astrophysical Observatory, the Smithsonian Center for Materials Research and Education, the Smithsonian Environmental Research Center, and the Smithsonian Tropical Research Institute.

The online version of Smithsonian Magazine [http://www.smithsonianmag.si.edu/] contains many of the same articles as its monthly counterpart. However, as it is a subscription product, the publicly available materials are a selection of the magazine's full content, not the complete content. Site contents include links to travel information, articles, an archive, and image files.

Search Tools

Direct Search, Science - Invisible Web
http://gwis2.circ.gwu.edu/~gprice/science.htm
Compiled and maintained by Web search guru Gary Price, George Washington University, Washington D.C. and Ashburn, VA.

Material "hidden" from the general search tools is said to reside on the Invisible Web. Direct Search is a growing compilation (a collection of many specialized searchable, interactive databases) of links to the search interfaces of these Invisible Web resources that contain data not easily or entirely searchable or accessible from general search tools like Alta Vista, Google, or HotBot. Subject areas include Aerospace/Astronomy, Biology, Botany, Chemistry, Computer Science, Environment, Geology, Global Change, Medicine/Health, Life Sciences, Material, Meteorology/Climatology, Nuclear, Oceanography, Pharmaceuticals/Drugs, Physics, R&D/Tech Transfer, Standards, Water Engineering, Wildlife, and Zoology. The site has links to searchable bibliographies in major library catalogs, as well as to other reference tools.

Google Index to Science and Technology
http://directory.google.com/Top/Science/
Categories available (number of links as of 15 June 2001) include Agriculture (2254), Anomalies and Alternative Science (588), Astronomy (3004), Biology (23418), Chemistry (2276), Conferences (33), Directories (56), Earth Sciences (6115), Educational Resources (264), Employment (96), Environment (5465), History of Science (251), Institutions (847), Instruments and Supplies (1147), Math (7850), Methods and Techniques (162), News (76), Physics (3462), Publications (162), Reference (247), Science in Society (554), Social Sciences (16597), Software (143), and Technology (10476).

Well known features of the Google search are its phone number look-up and the automatic presentation of English translations of French, German, Spanish and Portuguese Web pages. Less known but more important to users looking for science and technological information is Google's PDF Search. By simply beginning the search string with the phrase "inurl:pdf" users can turn a simple Google search into a Google PDF search, which allows searching of the visible and invisible Webs at the same time. Google's PDF database began with 13 million documents, PDF files that normal spidering or crawling of a Web site does not locate because of restrictions built into other engines. Documents retrieved in PDF format are immediately recognizable by the notation [PDF] appearing in front of them. The Google search engine searches not only the Web site, but also any PDF documents contained there in their entirety for query terms. In a Google search, retrieved PDF documents can be displayed as ASCII-text documents by choosing the "Text version" option. This feature is one to bear in mind when searching for scientific or research documents on the Web as many of them are available only in PDF format.

Jayde Science
http://www.jayde.com/guides/science/science.html
Jayde Online is a searchable directory that as of 15 June 2001 had 20 main Web guides and 200+ sub-categories in various science-related subject areas. More sub-categories will be added but only those that have mainstream interest. Subject areas covered include: Agriculture, Astronomy, Biology, Chemistry, Engineering, Genetics, Geography, Geology, Mathematics, Microbiology, Physics, and General Science.

The four search methods offered are Proximity searching, AND searching, OR searching, and PHRASE searching. The default search method is Proximity searching where a site listing is selected as a search match if the keywords searched are found within 20 words of each other within the site entry. The indexing method used by Jayde is somewhat different than the methods used by other search engines. Keyword submission is neither required nor permitted. Keywords are extracted automatically from site names and descriptions by the indexing software. The extraction process ignores irrelevant words such as the, a, and, by, for, etc. The ProIndex search engine software is configurable.

Additional Resources

A Short Dictionary of Scientific Quotations
http://naturalscience.com/dsqhome.html
It isn't often that a Web site is exactly what it says, but this is a definite exception. The initial page of this site is exactly that: a short collection - or dictionary as they are listed alphabetically by author - of scientific quotations. The fact that the site also has links to scientific cover stories, scientific articles, scientific news and books, a section of letters from people of all ages and nationalities, an open forum and a section on what's new in science are a bonus. The biggest bonus at this site is the link to its "Home."

Academic Press Dictionary of Science and Technology
http://www.harcourt.com/dictionary/
Contents of the dictionary range from scientific abbreviations to zoology, include most everything in between, and represent a total of 125 different fields. Main entry types include but are not limited to single-words, abbreviations, acronyms, proper names, geographical and biographical information, prefixes, suffixes, and combined forms.

"… the largest scientific dictionary ever compiled in the English language to the Web. Search from over 130,000 terms defined in 130 fields of science is a completely new and original work, not a revision or derivation of an older dictionary, and the entire text has been expressly written for this publication… the dictionary includes those terms that are likely to be encountered in a scientific context by an informed general reader."

Compendium of Chemical Terminology
http://www.chemsoc.org/chembytes/goldbook/index.htm
One of the series of IUPAC "Colour Books" on chemical nomenclature, terminology, symbols and units, and collects together terminology definitions from IUPAC recommendations already published in Pure and Applied Chemistry and in the other Colour Books. Sponsored by chemsoc - a brand new site for chemists and the home of the international chemistry societies' electronic network. Requires free registration. The site includes a source list and links to chemical societies, resources, periodic tables and other Web links.

"This online version [http://www.chemsoc.org/cgi-shell/empower.exe?DB=goldbook] of the IUPAC Compendium of Chemical Terminology corresponds to the second edition, compiled by Alan D. McNaught and Andrew Wilkinson (Royal Society of Chemistry, Cambridge, UK) and published in print form by Blackwell Science in 1997. Some minor errors have been corrected (the changes are noted where they occur), and cross-referencing has been improved. The conversion to electronic form was carried out by David Stout (Information Technology Consultant, Information Services, Royal Society of Chemistry).

Terminology definitions published by IUPAC are drafted by international committees of experts in the appropriate chemistry sub-disciplines, and ratified by IUPAC's Interdivisional Committee on Nomenclature and Symbols. In this edition of the Compendium these IUPAC-approved definitions are supplemented with some definitions from ISO and from the International Vocabulary of Basic and General Terms in Meterology; both these sources are recognised by IUPAC as authoritative. The result is a collection of nearly 7000 terms, with authoritative definitions, spanning the whole range of chemistry.

Verbal definitions of terms from Quantities, Units and Symbols in Physical Chemistry (the IUPAC Green Book, in which definitions are generally given as mathematical expressions) were developed specially for this Compendium by the Physical Chemistry Division of IUPAC. Definitions of a few physicochemical terms not mentioned in the Green Book were added at the same time (referred to here as Physical Chemistry Division, unpublished). A cross (+) against an entry implies that use of the term is discouraged.

The first reference given at the end of each definition is to the page of Pure Appl. Chem. or other source where the original definition appears; other references given designate other places where compatible definitions of the same term or additional information may be found, in other IUPAC documents. The complete reference citations are given in the appended list of source documents. Highlighted terms within individual definitions link to other entries where additional information is available."

Dictionary of Computing
http://foldoc.doc.ic.ac.uk/foldoc/contents.html

PrePRINT Network
http://www.osti.gov/preprint/
Sponsored and maintained by the U.S. Department of Energy. "PrePRINT Alerts harvests information from the Deep Web, offering a single-query portal to 340,000 preprints on 1,500 preprint servers in disciplines related to Department Of Energy (DOE) research. Such disciplines include the great bulk of physics, materials, and chemistry, as well as portions of biology, environmental sciences and nuclear medicine.

With a single query, users can search one or a selected set of existing preprint servers. The Network pulses the search engines of such servers, compiles the results, and returns them to the users. Preprints in the areas of physics, materials, chemistry, mathematics, biology, environmental sciences, and other areas related to DOE's research interests. Generally, preprints are manuscripts that have not yet been published, but may have been reviewed and accepted; submitted for publication; or intended for publication and being circulated for comment. Preprints may also be referred to as "e-prints." Many e-prints are electronic versions of research papers that have been submitted for dissemination and review among peers, for publication in journals, or prior to presentation at conferences. Some preprint servers may define preprints as any electronic work circulated by the author outside of the traditional publishing environment.

The PrePRINT Network offers the user several access mechanisms. Users may browse or search one specific preprint site, a selected set of sites, or all of the listed sites. There are two options for searching the PrePRINT Network. Search All Sites, allows users to search the HTML Web pages of the sites linked within the PrePRINT Network. This option returns hits for any surface Web pages that contain the specified terms. The second option, Search Selected Sites, provides simultaneous searching across selected preprint databases and servers. The PrePRINT Network pulses the search engines of each large preprint database and returns a compiled results list to the user. The Browse option allows users to view an alphabetical listing of all of the preprint sites included in the system and to visit any of the individual sites listed.

Within the Search section, users may choose to perform an indexed search of the HTML pages of the available sites that are continually updated. This option returns hits for any pages and for linked pages that contain the specified search term, including some items that may not be actual preprints. A second option for searching within the PrePRINT Network allows users to pulse the search engines of selected preprints sites with a single query. This search capability then returns a compiled results list.
The Subject Pathways option (these pages contain links to preprint servers or preprints provided by individual authors, which have been organized into subject-specific categories) offers users the ability to browse the preprints resources by subject area. This section includes both preprints servers and preprints posted by individual scientists on their own sites.

Lastly, the PrePRINT Alerts feature allows users to create personal profiles based on their interests. After specifying the search criteria and the preprint databases on which to run the search, the user will be automatically notified via email whenever new information is added to the chosen preprint resources. Users may wish to use the search selected sites (users search by author, title, or full record information from 1997-2001, using check boxes to indicate collections to search against) page to determine the best keywords and database prior to creating their alert.

The resources within the PrePRINT Network are provided by a variety of sources including academic institutions, government research laboratories, scientific societies, private research organizations, and individual scientists and researchers. The PrePRINT Network facilitates access to these resources. It does not change the content or data provided by the originating site or author in any way.

"As with other Internet sites, the preprints sites and resources may be transient in nature and may be modified or removed at the discretion of the site owners with or without prior notification. The preprints themselves are also dynamic. Many of them have not yet been peer reviewed, or are currently undergoing peer review. Substantial changes may occur prior to formal publication and it is possible that the preprint may not be formally published at all."
