A citation is a reference to a source. More precisely, a citation is an abbreviated alphanumeric expression embedded in the body of an intellectual work that denotes an entry in the bibliographic references section of the work for the purpose of acknowledging the relevance of the works of others to the topic of discussion at the spot where the citation appears.
An academic journal or scholarly journal is a periodical publication in which scholarship relating to a particular academic discipline is published. Academic journals serve as permanent and transparent forums for the presentation, scrutiny, and discussion of research. They nearly universally require peer review for research articles or other scrutiny from contemporaries competent and established in their respective fields.
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.
The Institute for Scientific Information (ISI) was an academic publishing service, founded by Eugene Garfield in Philadelphia in 1956. ISI offered scientometric and bibliographic database services. Its specialty was citation indexing and analysis, a field pioneered by Garfield.
The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as indexed by Clarivate's Web of Science.
The h-index is an author-level metric that measures both the productivity and citation impact of the publications, initially used for an individual scientist or scholar. The h-index correlates with success indicators such as winning the Nobel Prize, being accepted for research fellowships and holding positions at top universities. The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications. The index has more recently been applied to the productivity and impact of a scholarly journal as well as a group of scientists, such as a department or university or country. The index was suggested in 2005 by Jorge E. Hirsch, a physicist at UC San Diego, as a tool for determining theoretical physicists' relative quality and is sometimes called the Hirsch index or Hirsch number.
Geophysical Research Letters is a biweekly peer-reviewed scientific journal of geoscience published by the American Geophysical Union that was established in 1974. The editor-in-chief is Harihar Rajaram.
The Social Sciences Citation Index (SSCI) is a commercial citation index product of Clarivate Analytics. It was originally developed by the Institute for Scientific Information from the Science Citation Index. The Social Sciences Citation Index is a multidisciplinary index which indexes over 3,400 journals across 58 social science disciplines – 1985 to present, and it has 122 million cited references – 1900 to present. It also includes a range of 3,500 selected items from some of the world's finest scientific and technical journals. It has a range of useful search functions such as 'cited reference searching', searching by author, subject, or title. Whilst the Social Sciences Citation Index provides extensive support in bibliographic analytics and research, a number of academic scholars have expressed criticisms relating to ideological bias and its English-dominant publishing nature.
Nova Science Publishers is an academic publisher of books, encyclopedias, handbooks, e-books and journals, based in Hauppauge, New York. It was founded in 1985.

Cambridge Scientific Abstracts was a division of Cambridge Information Group and provider of online databases, based in Bethesda, Maryland, before merging with ProQuest of Ann Arbor, Michigan, in 2007. CSA hosted databases of abstracts and developed taxonomic indexing of scholarly articles. These databases were hosted on the CSA Illumina platform and were available alongside add-on products like CSA Illustrata. The company produced numerous bibliographic databases in different fields of the arts and humanities, natural and social sciences, and technology. Thus, coverage included materials science, environmental sciences and pollution management, biological sciences, aquatic sciences and fisheries, biotechnology, engineering, computer science, sociology, linguistics, and other areas.
The Web of Science is a paid-access platform that provides access to multiple databases that provide reference and citation data from academic journals, conference proceedings, and other documents in various academic disciplines. Until 1997, it was originally produced by the Institute for Scientific Information. It is currently owned by Clarivate.
