Mapping environmental voting research: dual-database bibliometric dataset and analysis code (1978–2026)

Companion data and code for the article "Mapping Environmental Voting Research: Trends, Intellectual Structure and the Limits of Single-Database Review." Contains the list of the 627 analysed documents (DOIs, year, source, database membership, citations), the derived data tables underlying all figures, the verbatim Web of Science and Scopus search queries, and the Python analysis scripts. The raw Web of Science and Scopus export files are not included, as these subscription databases do not permit redistribution of raw records; the corpus is fully reproducible from the included queries.
