Bibliometric databases

Web of Science – interdisciplinary bibliographic and abstract database of Clarivate (formerly Thomson Reuters), providing citation index for locating research across a curated, multidisciplinary set of journals, books,and conferences. The Web of Science platform is a paid-access platform for authorised users and is available under the national license from the website from the web page of the Adam Mickiewicz University Library in Poznan. The Web of Science Core Collection provides researchers, administrators, faculty, and students with quick, powerful access to the world’s leading citation databases and comprises the following index bases:

• Science Citation Index Expanded (SCIE),
• Social Sciences Citation Index (SSCI),
• Arts & Humanities Citation Index (AHCI),
• Conference Proceedings Citation Index – Science (CPCI-S),
• Conference Proceedings Citation Index – Social Science & Humanities (CPCI-SSH),
• Book Citation Index – Science (BKCI-S),
• Book Citation Index – Social Sciences & Humanities (BKCI-SSH),
• Emerging Sources Citation Index (ESCI),
• Current Chemical Reactions (CCR-EXPANDED),
• Index Chemicus (IC).

Scopus – is an interdisciplinary bibliographic and abstract database published by Elsevier and includes citation indexes. The Scopus database is a paid-access platform for authorised users and is available under the national license from the website from the web page of the Adam Mickiewicz University Library in Poznan.

Journal Citation Reports (JCR) – is an interdisciplinary bibliometric database available from the Web of Science (Clarivate) platform, in which yearly rankings of scholarly journals are published. The database also provides Impact Factor citation indexes. The JSR database is a paid-access platform for authorised users and is available under the national license from the website from the web page of the Adam Mickiewicz University Library in Poznan.

Bibliometric indicators

Impact Factor (IF) – or journal impact factor (JIF) of an academic journal is a scientometric index on the Web of Science platform 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 IF is published in the Journal Citation Reports database. The Journal Impact Factor indicator is counted based on WoS citations. Impact Factors can be searched in Journal Citation Reports -database. The Impact Factor indicator for a given journal is calculated by dividing the number of cited scholarly articles from the last two years by the total number of articles published in this journal within the same date frame. The IF is calculated at the end of the year and then published mid-year the following year.

Indeks Hirscha (h-index)– The h-index is defined as the maximum value of h such that the given author/journal has published at least h papers that have each been cited at least h times, e.g. the h index = 10 means that the author has 10 publications that are cited at least 10 times. This measure was developed by Jorge Hirsch and introduced in 2005.

CiteScore – is a citation indicator for scholarly journals. The Cite Score is an indicator available in Scopus, and therefore journals indexed in Scopus (Elsevier) are taken into account in the calculation. The SJR index is a scientific journal prestige indicator. The CiteScore index for a given year defines the average number of citations from the last 3 years divided by the number of documents published within the same 3-year period.

SJR (SCImago Journal Rank) – – the SJR index is a measure that establishes the quality of scientific publications according to the weighted citations received by a journal. SJR index, and is calculated based on the data from Scopus citation database (Elsevier). These indicators can be used to assess and analyse the particular scientific domain a given journal represents assigning more weight to citations coming from journals with higher SJRs, i.e. citations that come from journals in the same or similar domains have the advantage over citations from journals of non-related research areas, as with greater probability the former represent more merit-oriented citations.

SNIP (Source Normalized Impact per Paper) – is a normalised index (indicator) to determine the number of citations of a given scholarly journal with regard to its domain and is published in the Scopus (Elsevier) database. The value of the SNIP indicator is the quotient of the average number of citations form a given year that refer to the publications from the last 3 years and the citation potential in a given scientific domain.

Journal Citation Indicator (JCI) – is a normalised metrics with regard to a given scientific domain, calculated for all journals indexed in the Web of Science Core Collection. The JCI cohesiveness is provided by the representation of the average citation impact normalised for a given category for works published within the last three years. The JCI factor was introduced for the first time in 2021.

Citation index (number of citations) – is a normalised metrics with regard to a given scientific domain, calculated for all journals indexed in the Web of Science Core Collection. The JCI cohesiveness is provided by the representation of the average citation impact normalised for a given category for works published within the last three years. The JCI factor was introduced for the first time in 2021. Analizę cytowań wraz z określeniem h-indexu można przeprowadzić za pomocą: bazy Web of Science (Clarivate), bazy Scopus (Elsevier), wyszukiwarki Google Scholar (nakładka Google Scholar Citations), programu „Publish or Perish”.

Bibliometric indicators

InCites – a tool to analyse scholarly output of research institutions on the basis of data provided by the Web of Sciences Core Collection. The tool supports research assessment with reliable evidence and benchmarks a given institution’s research against peers. Access to InCites is available to authorized users under the national license from the web site of the University Library in Poznań.

SciVal– a tool that provides comprehensive analysis of data on research and scholarly publications published by research institutions on the basis of lists of indexed publications in the Scopus (Elsevier) database. Access to SciVal is available for authorised users under the national .license from the website of the University Library in Poznań.

Publish or Perish – – is a software program, using Google Scholar data, that retrieves and analyses academic citation, thus determining a number of bibliometric indicators, such as the number of papers, the h-index and total citations. Access to the program is free but requires downloading the application onto your computer and appropriate operating system.

Google Scholar Citations – – is a plug-in for Google Scholar and lets authors set up a profile page that lists their publications and citation metrics in Google Scholar, including the calculation of the h-index. The citation metrics are updated automatically. Google Scholar Citations is a citation service provided free of charge

Bibliometric analyses

The Scientometrics Centre offers the following bibliometric analyses for AMU research staff tailored to individual use cases:

• number of citations,
• calculation of the h-index.

In addition, we offer services in having bibliometric indicators for periodicals and journals scrutnised for the research quality, using the Journal Citation Reports (Web of Science) and Scopus databases, and in calculating scores for publications in keeping with the current ministerial listing.
