- General Conclusion
Scientific and scholarly authors normally cite other publications. They do so by providing bibliographical references to other → documents in the text and elaborating them in a special “list of references” (as in this encyclopedia article) or in footnotes. (Such references are also often in the bibliometric literature termed “cited references”). Wh...
In the words of Weinstock (1971, 16): “a citation index is a structured list of all the citations in a given collection of documents. Such lists are usually arranged so that the cited document is followed by the citing documents”. It is the scientist (or scholar) who creates the citations not the citation indexes as it has been claimed , and the ro...
In this article citation indexes are presented in the following order: 1. Section 4 presents the Science Citation Indexand later ISI/Clarivate Analytics citation indexes in chronological order; 2. Section 5presents citation databases from other database producers (except regional databases) in chronological order; 3. Regional citation databases (an...
The American government stimulated the development of scientific research soon after World War II. Considering the fast-growing volume of scientific literature and their concern regarded to the systems for information exchange capacity among scientists, the government sponsored many projects related to the improvement of methods for distributing an...
5.1 CiteSeerX
CiteSeerX (until 2006 called Cite Seer) is an autonomous and automatic citation indexing system introduced in 1997. It focusses primarily on the literature in computer and information science. CiteSeerX was an innovation from previous citation indexing systems because the indexing process is completely automatic. The citation index autonomously locates, parses, and indexes articles found on the World Wide Web. CiteSeerX was based on these features: actively acquiring new documents, automatic...
5.2 Crossref
Crossref (or CrossRef) was launched in early 2000 by the Publishers International Linking Association Inc. (PILA) as a cooperative effort among publishers to enable persistent cross-publisher citation linking in online academic journals by using the Digital Object Identifier (DOI) . PILA is a non-profit organization that provides citation links for both open access journals and subscription journals for online publications by the contributing publishers (but access to the subscription journal...
5.3 Scopus Citation Index
Elsevier released Scopus in 2004. Jacso (2005, 1539) wrote about it: Sugimoto and Larivière (2018, 30) wrote about this: “The establishment of Scopus is often heralded as a successful case of vertical integration, in which the firm that creates the citation index also owns the material it is indexing”. The database presents itself as “the largest abstract and citation database of peer-reviewed literature: scientific journals, books and conference proceedings” . One important aspect described...
ISI and its successor Thomson ISI seem to have had a de facto monopoly on citation indexes from the early 1960s until about 2000 (disregarding Shepard’s Citations, cf., Section 7.1). Thereafter other citation indexes began to appear. As already stated, PsycInfo began adding citation information to its database in 2001. At that time, it was rather u...
It was the SCIthat made citation indexes central to information science; only retrospectively it has been considered important to look back and recognize the earlier citation indexes, and therefore, this section is placed after the others. Garfield (1979, 7) acknowledges that “Shepard’s Citations is the oldest major citation index in existence; it ...
There is a strong connection between the information retrieval domain and subject access points (SAP) . Two kinds of SAP should be distinguished for this discussion of citation indexes: 1. Terms, either assigned to documents by indexers (e.g., descriptors from → thesauri) or derived from the document (e.g., words from titles, e.g., in so-called KWI...
In scholarly communication, referencing previous works is an indispensable part of a document that reports research. As Ziman (1968, 58) wrote: “a scientific paper does not stand alone; it is embedded in the ‘literature’ of the subject”. From the point of view of using the citations for information retrieval, it is important to consider the citatio...
Orduña-Malea and Delao-López-Cózar (2018) expressed some views, which we find serve as a proper conclusion for this article. They mentioned the importance of tools such as telescopes and microscopes for the development of science and they related the importance of citation indexes for the understanding of the ecosystem of scientific information wit...
