The Web of Knowledge platform provides access to:

  • Web of Science with
    • Science Citation Index: a multidisciplinary database covering all sciences (incl. maths, computing, physics & astronomy, chemistry, earth & biological sciences, medicine & engineering); indexes over 6650 journals and is updated with 16,000 new records every week. Data available from 1945.
    • Conference Proceedings Citation Index: indexes the published literature of the most significant conferences, symposia, seminars, colloquia, workshops, and conventions in a wide range of disciplines in science and technology. Published proceedings may be included from a number of sources: books or series produced by publishers or societies, reports, sets of preprints (when preprints are the only publications from a conference) or journals. Data from 1990; more than 1100 conferences added each quarter.
  • Journal Citation Reports (JCR): provide citation data, journal ranking and impact factors for nearly 5,000 leading science journals and "provide a systematic and objective means of determining the relative importance of science journals within their subject categories".
    • 2015 Journal Citation Reports now available - search here
    • Impact Factors are calculated by ISI from the data in their Citation Indexes: "The journal impact factor is a measure of the frequency with which the 'average article' in a journal has been cited in a particular year. The impact factor will help you evaluate a journal's relative importance, especially when you compare it to others in the same field. The impact factor is calculated by dividing the number of current citations to articles published in the two previous years by the total number of articles published in the two previous years".
  • Essential Science Indicators: a database of performance statistics and trends in science, providing citation rankings for scientists, institutions, countries, journals and papers

Searching Notes

  1. Topic (subject) search: abstracts are available only from 1991 onwards in Science Citation Index, and only when provided by the author in English in the original article; otherwise, topic searches are only carried out on article titles plus a few added keywords.
  2. Address information is only included in Science Citation Index records from 1973 onwards, so a search including address terms will not retrieve earlier records.

  • Save a search history as an alert, which will deliver search results to you each week by email

N.B. The Web of Science Science Citation Index database is multidisciplinary and does not cover chemistry in as much depth as Chemical Abstracts / SciFinder Scholar - fewer chemical journals are covered, patents are not included, it does not cover as many years, and chemical compounds and reactions are not indexed. For further details and examples see: Science Citation Index / Web of Science v. Chemical Abstracts / SciFinder Scholar: Comparison of Features and retrieval rates.
