Supplementary data on journal quartiles and citation indicators across disciplines

This dataset provides supplementary data extracted and processed from the SCImago Journal Rank portal (2023) and the Scopus Discontinued Titles list (February 2025). It includes journal-level metrics such as SJR and h-index, quartile assignments, and subject category information. The files are intended to support exploratory analysis of citation patterns, disciplinary variations, and structural characteristics of journal evaluation systems. The dataset also contains Python code and visual materials used to examine relationships between prestige metrics and cumulative citation indicators.
