My RI - Measuring your Research Impact. Citation searching.
Citation databases such as Web of Science and Scopus allow you to search for articles that have cited a particular paper or papers. Citations are references made to earlier work by an author in their own paper. You can therefore see how a piece of work has influenced further work and investigations. This essentially enables you to go forward in time by viewing who cited a particular paper or go back in time by viewing the papers cited by a particular paper.
The advantage of citation searching over a traditional database search is demonstrated in this image produced by Thomson Reuters, formerly ISI, who produced the first ever citation database Science Citation Index in 1961.
