Further suggestions might be found on the article's talk page . Scopus Scopus is a scientific abstract and citation database , launched by the academic publisher Elsevier as a competitor to older Web of Science in 2004. An ensuing competition between

90-522: A new headquarters north of campus. Ground was broken in 1971 for an expansion to the building designed by architects Brubaker/Brandt to accommodate the review of 400,000 new research reports printed each year. The 5-story 142,000 square foot building opened in May 1973. In 2007, the ACS designated its Chemical Abstracts Service subdivision an ACS National Historic Chemical Landmark in recognition of its significance as

120-476: A profile and a facility to calculate authors' h -index . In 2016, a gratis website, Scopus CiteScore, was introduced. It provides citation data for all 25,000+ active titles such as journals, conference proceedings and books in Scopus and provides an alternative to the impact factor , a journal-level indicator which may correlate negatively with reliability. Scopus IDs for individual authors can be integrated with

150-475: A selected journal. Also included is its language of text and language of summaries. The range is from 1907 to the present, including both serial and non-serial scientific and technical publications. The database is updated quarterly. Beyond CASSI lists abbreviated journal titles from early chemical literature and other historical reference sources. Chemical Abstracts ( CA ) began as a volunteer effort and developed from there. The use of volunteer abstractors

180-438: A small number of publications are actually indexed for chemical structure searches. SciFinder is the preferred option for chemical searches is all cases. Scopus also offers author profiles which cover affiliations, number of publications and their bibliographic data, references , and details on the number of citations each published document has received. It has alerting features that allow registered users to track changes to

210-402: Is a measure reflecting the yearly average number of citations to recent articles published in that journal. It is produced by Elsevier , based on the citations recorded in the Scopus database. Absolute rankings and percentile ranks are also reported for each journal in a given subject area. An article published by "Scholarly Criticism" in 2024 alleges that Elsevier unethically indexed

240-469: Is a database of chemical and bibliographic information. Originally it was available only as a client application (for both Windows and MacOS operating systems), a web version was released in 2008. By that time it had a graphical interface, and was able to do graphical searches for chemical structures and reactions (the first database to allow such functions), as well as keyword searches for literature in chemistry and related disciplines. SciFinder Scholar

270-409: Is all-inclusive." A small number of studies found ca. 80-90% overlap in coverage between WoS and Scopus for the period between 1990 and 2020. In terms of the structured query language search capabilities Scopus is somewhat more advanced than Web of Science : for example, WoS can perform only NEAR/n queries, Scopus can also do PRE/n queries. Also, when the same article was covered in Scopus and in

300-408: Is needed in order to fully take advantage of SciFinder capabilities. CASSI stands for Chemical Abstracts Service Source Index . Since 2009, this formerly print and CD-ROM compilation is available as a free online resource to look up and confirm publication information. The online CASSI Search Tool provides titles and abbreviations, CODEN , ISSN , publisher , and date of first issue (history) for

330-685: Is updated 2 to 3 times per year. Each year Scopus receives around 3,500 submissions for new titles to be included and accepts approximately 25% of them. The re-evaluation policy is based on four criteria of Publication Concern, Under Performance, Outlier Performance and Continuous curation. Between 2004 and 2020, Scopus included 41,525 and excluded 688 titles Between 2016 and 2023, the CSAB has re-evaluated 990 titles published by 539 different publishers, leading to 536 titles discontinued for indexing. In 2024 Scopus covered around 28,000 active journals and nearly 300,000 books. Nevertheless, research continues to show

360-529: The National Institutes of Health . The chemical information is produced by CAS, and is prepared by the CAS Registry System, which identifies each compound with a specific CAS registry number , index name, and graphic representation of its chemical structure. The assignment of chemical names is done according to the chemical nomenclature rules for CA index names, which is slightly different from

390-577: The Web of Science (WOS), a 2006 study concluded that Scopus is "easy to navigate, even for the novice user. ... The ability to search both forward and backward from a particular citation would be very helpful to the researcher. The multidisciplinary aspect allows the researcher to easily search outside of his discipline" and "One advantage of WOS over Scopus is the depth of coverage, with the full WOS database going back to 1945 and Scopus going back to 1966. However, Scopus and WOS complement each other as neither resource

420-411: The Web of Science (WoS), its Scopus entry had a keyword ratio 3-5 of than its WoS counterpart, and the Scopus keywords are more focused on the specific article content, whereas WoS has more keywords related to the broad category of the article's subject. A larger number of narrow-targeted keywords allows Scopus users to find a larger number of relevant publications, while filtering out false positives. On

450-565: The different products are CAplus and Registry. CAS References consists of bibliographic information and abstracts for all articles in chemical journals worldwide, and chemistry-related articles from all scientific journals, patents, and other scientific publications. As of 2023 , the CAS Registry contains information on more than 200 million organic and inorganic substances, and about 70 million protein and nucleic acid sequences . The sequence information comes from CAS and GenBank , produced by

480-415: The inclusion of predatory journals . While marketed as a global point of reference, Scopus and WoS have been characterised as "structurally biased against research produced in non-Western countries, non-English language research, and research from the arts, humanities, and social sciences". or Science-wide author databases of standardized citation indicators CiteScore (CS) of an academic journal

510-490: The internationally standard IUPAC names , according to the rules of IUPAC . CAS databases are available via two principal database systems, STN, and SciFinder. STN (Scientific & Technical Information Network) International is operated jointly by CAS and FIZ Karlsruhe , and is intended primarily for information professionals, using a command language interface. In addition to CAS databases, STN also provides access to many other databases, similar to Dialog . SciFinder

540-705: The journal Heliyon , which is published by Elsevier's subsiduary, in Scopus within a few months of its launch. This indexing occurred with one citation and four published issues in 2015, which the article suggests does not align with the rules prescribed for other journals. The article further alleges that Elsevier was motivated to engage in this practice, which the article calls a "conflict of interest," in order to attract authors to publish in Heliyon, which charges an article processing charge of USD 2,100 per publication. In 2024 French National Centre for Scientific Research CNRS ended its subscription to Scopus, while maintaining for

570-407: The journals listed in Scopus are considered to meet the requirement for peer review quality established by several research grant agencies for their grant recipients and by degree -accreditation boards in a number of countries. Scopus also allows patent searches from a dedicated patent database, Lexis-Nexis , albeit with limited functionality. Comparing ease of use and coverage of Scopus and

600-468: The non-proprietary digital identifier ORCID . In 2018, Scopus started embedding partial information about the open access status of works, using Unpaywall data. However, Scopus' ris export files do not contain the information about Open Access status. Since Elsevier is the owner of Scopus and is also one of the main international publishers of scientific journals, an independent and international Scopus Content Selection and advisory board (CSAB)

630-454: The other hand, WoS exports (e.g. in the ris format) the doi numbers of cited articles, while Scopus exports the titles of cited articles. Also, Scopus allows exporting 20,000 references (e.g. as a ris file) at once, while WoS export is limited to 5,000 references at once. Scopus provides chemical search by CAS number and by chemical name, while WoS does not have these features. On the other hand, WoS has chemical structure search, but only

660-1073: The that year its subscription to Web of Science . This decision was allegedly motivated by a greater use of Web of Science by CNRS's employees. SciFinder Chemical Abstracts Service ( CAS ) is a division of the American Chemical Society . It is a source of chemical information and is located in Columbus, Ohio , United States . Chemical Abstracts is a periodical index that provides numerous tools such as SciFinder as well as tagged keywords, summaries, indexes of disclosures, and structures of compounds in recently published scientific documents. Approximately 8,000 journals , technical reports , dissertations , conference proceedings , and new books , available in at least 50 different languages, are monitored yearly, as are patent specifications from 27 countries and two international organizations. Chemical Abstracts ceased print publication on January 1, 2010. The two principal databases that support

690-520: The two databases has been characterized as "intense" and is considered to significantly benefit their users in terms of continuous improvent in coverage, search/analysis capabilities, but not in price. Free database The Lens completes the triad of main universal academic research databases. Journals in Scopus are reviewed for sufficient quality each year according to four numerical measures: h -Index , CiteScore , SJR ( SCImago Journal Rank ) and SNIP ( source normalized impact per paper ). For this reason,

720-559: The west bank of the Olentangy River , just north of The Ohio State campus. This campus became well known in the Columbus area and famous as the site of many Columbus Symphony Orchestra pop concerts. In 2009, the campus consisted of three buildings. In 1907, William A. Noyes had enlarged the Review of American Chemical Research , an abstracting publication begun by Arthur Noyes in 1895 that

750-477: Was a key factor in its long-term success. Dale B. Baker became the CAS Director upon Crane's retirement in 1958. According to CAS, his visionary view of CAS' potential "led to expansion, modernization, and the forging of international alliances with other information organizations." CAS was an early leader in the use of computer technology to organize and disseminate information. The CAS Chemical Registry System

780-551: Was a very similar a product developed for academic institutions, but discontinued in 2023. In 2017 the ACS released SciFinder-n as a web-only product with the same data content and improved user interface and search functions. SciFinder is considered as the best source of chemical information worldwide, with substantially larger number of relevant information sources than Web of Science or Scopus with Reaxys . However, due to its unique and unusual search functions, substantial training

810-484: Was established in 2009 to prevent a potential conflict of interest in the choice of journals to be included in the database and to maintain an open and transparent content coverage policy, regardless of publisher. The board consists of scientists and subject librarians. Nevertheless, critique over a perceived conflict of interest has continued. CSAB team is responsible for inclusion and exclusion of different titles on Scopus. The list of journals and books indexed in Scopus

840-401: Was introduced in 1965. CAS developed a unique registry number to identify chemical substances. Agencies such as the U.S. Environmental Protection Agency and local fire departments around the world now rely on these numbers for the definite identification of substances. According to the ACS, this is the largest chemical substance database in the world. In 1965, CAS left their offices at OSU for

870-474: Was phased out in 1994. Chemical Abstracts has been associated with the American Chemical Society in one way or another since 1907. For many years, beginning in 1909, the offices of Chemical Abstracts were housed in various places on the Columbus, Ohio campus of Ohio State University , including McPherson Laboratory and Watts Hall . In 1965, CAS moved to a new 50-acre (200,000 m ) site on

900-401: Was the forerunner of Chemical Abstracts . When it became evident that a separate publication containing these abstracts was needed, Noyes became the first editor of the new publication, Chemical Abstracts . E. J. Crane became the first Director of Chemical Abstracts Service when it became an American Chemical Society division in 1956. Crane had been CA editor since 1915, and his dedication
