  Purpose: This study focuses on the changes in differences in the journal
coverage, visibility and prestige of journals from top twenty countries in Web
of Science and Scopus in the twenty-year timeframe-2001-2020. Methodology:
Using Web of Science and Scopus journal data from Journal Citation Reports and
Scimago Journal Rank, respectively, top twenty countries by number of journals
indexed in the two databases were identified. Analysis of the changes that
occurred in the number of journals from the top twenty countries, the citations
they received and their prestige were analyzed. Findings: USA and UK continued
their dominance of the journals indexed in Web of Science and Scopus, but their
dominance waned gradually in the course of the twenty-year period. The rate of
growth of journals indexed by the databases is steeper among the countries
outside the top. In Web of Science, journals from the UK were the most
prestigious until 2010 when China emerged as the most prestigious journals. USA
continues to take the leading spot in terms of most prestigious journals in
Scopus, followed by UK. Research Limitations: This investigation relied on
third-party datasets sourced from the Scimago Journal Rank repository for the
compilation of the Scopus journal list. Practical implications: This study
suggests an inclination towards diversity by Web of Science and Scopus, though
North America and Europe continue to dominate journal coverage. However, the
gulf in the prestige and visibility of journals from North America, Europe and
other parts of the world remains, suggesting the researchers from the
peripheral may continue to gravitate towards the core. Originality/Value: While
studies have provided singular-year analyses of journal coverages of Web of
Science and Scopus, this study provides an analysis of 20 years.
