Citation analysis, also called citation tracking or cited reference searching, involves identifying articles, books, or other materials that have cited a specific work. Citation analysis helps determine how much impact a particular scholarly work has had. There are a number of tools available; however, no single database covers all works that cite other works. Searching across several databases is necessary to ensure complete coverage.
Research Output Type -- Artists and designers often do not produce traditional textual work that can then be easily cited or referenced by other scholars. Instead, artists and designers may have a visual work published within someone else's textual scholarship, or have their visual work mentioned, critiqued, reviewed, or otherwise publicized elsewhere.
Document Format -- Art, architecture, and design fields remain heavily print based disciplines. Periodicals and books published in these disciplines are often available in print only format.
Publishing Culture -- The social sciences and humanities tend to cite more slowly, and often cite older research.
Discipline -- "social science and humanities disciplines tend to cite more slowly...Citation metrics should not be compared across disciplines unless this is accounted for..."
Document Type -- "Review papers tend to attract the most citations; case studies tend to attract the fewest citations."
Age of Research Cited -- "Older articles [and older researchers] will have more citations."
Data Source -- The number of citations will vary from one data source to another (i.e. Web of Science, Scopus, Google Scholar).
