A citation index is a kind of bibliographic index, an index of citations between publications, allowing the user to easily establish which later documents cite which earlier documents. A form of citation index is first found in 12th-century Hebrew religious literature. Legal citation indexes are found in the 18th century and were made popular by citators such as Shepard's Citations (1873). In 1961, Eugene Garfield's Institute for Scientific Information (ISI) introduced the first citation index for papers published in academic journals, first the Science Citation Index (SCI), and later the Social Sciences Citation Index (SSCI) and the Arts and Humanities Citation Index (AHCI). American Chemical Society converted its printed Chemical Abstract Service into internet-accessible SciFinder in 2008. The first automated citation indexing was done by CiteSeer in 1997 and was patented. Other sources for such data include Google Scholar, Microsoft Academic, Elsevier's Scopus, and the National Institutes of Health's iCite.
Bibliometrics is the use of statistical methods to analyse books, articles and other publications, especially in scientific contents. Bibliometric methods are frequently used in the field of library and information science. Bibliometrics is closely associated with scientometrics, the analysis of scientific metrics and indicators, to the point that both fields largely overlap.
Derek John de Solla Price was a British physicist, historian of science, and information scientist. He was known for his investigation of the Antikythera mechanism, an ancient Greek planetary computer, and for quantitative studies on scientific publications, which led to his being described as the "Herald of scientometrics".
Scientometrics is the field of study which concerns itself with measuring and analysing scholarly literature. Scientometrics is a sub-field of informetrics. Major research issues include the measurement of the impact of research papers and academic journals, the understanding of scientific citations, and the use of such measurements in policy and management contexts. In practice there is a significant overlap between scientometrics and other scientific fields such as information systems, information science, science of science policy, sociology of science, and metascience. Critics have argued that over-reliance on scientometrics has created a system of perverse incentives, producing a publish or perish environment that leads to low-quality research.
Citation analysis is the examination of the frequency, patterns, and graphs of citations in documents. It uses the directed graph of citations — links from one document to another document — to reveal properties of the documents. A typical aim would be to identify the most important documents in a collection. A classic example is that of the citations between academic articles and books. For another example, judges of law support their judgements by referring back to judgements made in earlier cases. An additional example is provided by patents which contain prior art, citation of earlier patents relevant to the current claim.
Eugene Eli Garfield was an American linguist and businessman, one of the founders of bibliometrics and scientometrics. He helped to create Current Contents, Science Citation Index (SCI), Journal Citation Reports, and Index Chemicus, among others, and founded the magazine The Scientist.
Informetrics is the study of quantitative aspects of information, it is an extension and evolution of traditional bibliometrics and scientometrics. Informetrics uses bibliometrics and scientometrics methods to study mainly the problems of literature information management and evaluation of science and technology. Informetrics is an independent discipline that uses quantitative methods from mathematics and statistics to study the process, phenomena, and law of informetrics. Informetrics has gained more attention as it is a common scientific method for academic evaluation, research hotspots in discipline, and trend analysis.
Howard D. White is a scientist in library and information science with a focus on informetrics and scientometrics.
Citation impact or citation rate is a measure of how many times an academic journal article or book or author is cited by other articles, books or authors. Citation counts are interpreted as measures of the impact or influence of academic work and have given rise to the field of bibliometrics or scientometrics, specializing in the study of patterns of academic impact through citation analysis. The importance of journals can be measured by the average citation rate, the ratio of number of citations to number articles published within a given time period and in a given index, such as the journal impact factor or the citescore. It is used by academic institutions in decisions about academic tenure, promotion and hiring, and hence also used by authors in deciding which journal to publish in. Citation-like measures are also used in other fields that do ranking, such as Google's PageRank algorithm, software metrics, college and university rankings, and business performance indicators.
Bibliographic coupling, like co-citation, is a similarity measure that uses citation analysis to establish a similarity relationship between documents. Bibliographic coupling occurs when two works reference a common third work in their bibliographies. It is an indication that a probability exists that the two works treat a related subject matter.
The Science Citation Index Expanded – previously titled Science Citation Index – is a citation index originally produced by the Institute for Scientific Information (ISI) and created by Eugene Garfield.
Louis André (Loet) Leydesdorff (21 August 1948, Batavia was a Dutch sociologist, cyberneticist, communication scientist and Professor in the Dynamics of Scientific Communication and Technological Innovation at the University of Amsterdam. He is known for his work in the sociology of communication and innovation, especially for his Triple helix model of innovation developed with Henry Etzkowitz in the 1990s.
Scientometrics is a monthly peer-reviewed academic journal covering the field of scientometrics. It publishes original studies, short communications, review papers, letters to the editor, and book reviews. It is published by Akadémiai Kiadó and Springer Science+Business Media and was established in 1978. Its founder and first editor-in-chief was Tibor Braun.
The International Society for Scientometrics and Informetrics was founded in 1993 in Berlin at the International Conference on Bibliometrics, Informetrics and Scientometrics. It is an association for professionals in the field of scientometrics.
A bibliometrician is a researcher or a specialist in bibliometrics. It is near-synonymous with an informetrican, a scientometrican and a webometrician, who study webometrics.
Blaise Cronin is an Irish-American information scientist and bibliometrician. He is the Rudy Professor Emeritus of Information Science at Indiana University, Bloomington, where he was Dean of the School of Library and Information Science for seventeen years. From 1985 to 1991 he held the Chair of Information Science and was Head of the Department of Information Science at the University of Strathclyde in Glasgow, U.K.
Wolfgang Joachim Emil Glänzel is a German statistician who is a full professor at KU Leuven, where he is also the director of the Centre for R&D Monitoring. In 1999, he and Henk Moed received the Derek de Solla Price Memorial Medal from the International Society for Scientometrics and Informetrics (ISSI). Currently, he is the editor-in-chief of Scientometrics, as well as secretary-treasurer of the ISSI. In that role, he took the controversial decision to withdraw an article under pressure by a commercial publisher criticized in that paper and partly owned by the publisher of his journal.

Ronald Rousseau is a Belgian mathematician and information scientist. He has obtained an international reputation for his research on indicators and citation analysis in the fields of bibliometrics and scientometrics.
The Leiden Manifesto for research metrics (LM) is a list of "ten principles to guide research evaluation", published as a comment in Volume 520, Issue 7548 of Nature, on 22 April 2015. It was formulated by public policy professor Diana Hicks, scientometrics professor Paul Wouters, and their colleagues at the 19th International Conference on Science and Technology Indicators, held between 3–5 September 2014 in Leiden, The Netherlands.
