A citation analysis of the research reports of the Central Mining Institute. Mining and Environment using the Web of Science, Scopus, BazTech, and Google Scholar: A case study

This paper presents the analysis of a Polish mining sciences journal (Prace Naukowe GIG. Gornictwo i trodowisko; title in English: Research Reports of the Central Mining Institute. Mining and Environment; acronym in English [RRCMIME]). The analysis is based on data from the following sources: the Web of Science (WoS), Scopus, BazTech (a bibliographic database containing citations from Polish Technical Journals), and Google Scholar (GS). The data from the WoS and Scopus were collected manually as RRCMIME is not indexed in these sources. GS does index BazTech; however, research shows that only 84% of BazTech citations are available through GS. Therefore, this may suggest that the most recommended sources for the bibliometric analyses of domestic journals, which are not indexed in international databases, are national data sources.
