Bigger Isn't Always Better: Dimensions Indexes More Journals, But Scopus Still Wins on Citations for Some Countries

Web of Science has the most selective journal coverage, while Dimensions is the most exhaustive. While generally Dimensions has higher research output, Scopus shows higher citation counts for China and India, likely due to subject area coverage differences across the databases.

Explícamelo como si tuviera cinco años

Scientists found that different online libraries of science papers collect different things. One library is very picky, only choosing the best papers, while another tries to collect almost every paper ever. Even though the "everything" library has more papers, a different library had more famous papers from China and India.

Limitaciones identificadas

Conservative Matching Procedure
The study uses a conservative matching procedure for journals, which might lead to some journals being classified as unique when they are essentially the same but spelled differently. This could slightly underestimate the overlap between databases.
Limited Scope (Journals Only)
The analysis focuses solely on journal coverage and does not consider other publication types like books and conference proceedings. This limits the scope of the comparison and might not fully capture the differences in coverage between databases.
Broad Subject Area Mapping
While the study uses article-level subject classification for Dimensions, it maps Scopus and Web of Science subject areas to broad categories, potentially masking finer-grained differences in subject coverage.
Exclusion of ESCI
The Emerging Sources Citation Index (ESCI) is not included in the analysis for Web of Science, potentially underestimating its coverage, especially for newer or less established journals.

Explicación de la calificación

This is a solid comparative analysis of journal coverage across three major databases. The methodology is sound and the findings are useful for researchers. The limitations, while present, don't significantly detract from the value of the analysis. The comparison offers a valuable update on previous research and provides new insights into the coverage of Dimensions.
