ISI Web of Knowledge is an academic citation indexing and search service, which is combined with web linking and provided by Thomson Reuters. Web of Knowledge coverage encompasses the sciences, social sciences, arts and humanities. It provides bibliographic content and the tools to access, analyze, and manage research information. A notable attribute is that multiple databases can be searched simultaneously.[1][2]

Overview
It is described as a unifying research tool which enables the user to acquire, analyze, and disseminate database information in a timely manner. This is accomplished because of the creation of a common vocabulary for varied search terms and varied data. Moreover, search terms generate related information across categories.
Acceptable content for the Web of Knowledge is determined by an evaluation and selection process based on the following criteria: impact, influence, timeliness, peer review, and geographic representation.[1]
Search and analysis
Web of Knowledge employs various notable search and analysis capabilities. First, Citation indexing is employed, which is enhanced by the capability to search for results across disciplines. The influence, impact, history, and methodology of an idea can be followed from its first instance, notice, or referral to the present day. This technology points to a deficiency with the keyword-only method of searching. Second, subtle trends and patterns, relevant to the literature or research of interest become apparent. Broad trends indicate significant topics of the day, as well as the history relevant to both the work at hand, and particular areas of study. Third, trends can be graphically represented. [1][3]

The database includes the following:
- 23,000 academic and science journals (Including Web of Science journal listings)
