The seven citation indices listed above contain references which have been cited by other articles.
One may use them to undertake cited reference search, that is, locating articles that cite an earlier, or current publication.In this way, current trends, patterns, and emerging fields of research can be assessed.Eugene Garfield, the "father of citation indexing of academic literature,"Citations are the formal, explicit linkages between papers that have particular points in common. It lists publications that have been cited and identifies the sources of the citations.In addition, literature which shows the greatest impact in a particular field, or more than one discipline, can be easily located through a citation index.For example, a paper's influence can be determined by linking to all the papers that have cited it.The simplicity of citation indexing is one of its main strengths.Web of Science is described as a unifying research tool which enables the user to acquire, analyze, and disseminate database information in a timely manner.Since 2008, the Web of Science hosts a number of regional citation indices.The Chinese Science Citation Database, produced in partnership with the Chinese Academy of Sciences, was the first one in a language other than English.This is accomplished because of the creation of a common vocabulary, called ontology, for varied search terms and varied data.Moreover, search terms generate related information across categories.
