A Reproducible Workflow Layer for 'Scopus' Bibliographic Searches R package scopusflow version 0.4.0 A coherent, quota-aware workflow layer over the Elsevier 'Scopus' Search 'API' <https://dev.elsevier.com/sc_apis.html>. It builds reproducible search plans, retrieves records with rate-limit handling, retry with back-off and optional resumable caching, normalises results to a stable tidy schema, extracts and tracks changes in Digital Object Identifiers (DOIs), sizes sets of concepts and their intersections, compares publication trends across topics, writes the search up as a reproducible record for a methods section following the 'PRISMA-S' reporting standard (Rethlefsen and others, 2021) <doi:10.1186/s13643-020-01542-z> and exports to formats compatible with downstream bibliometric tools. Network and 'API' errors are surfaced as typed conditions so that callers can respond to them programmatically. 'Scopus' is a trademark of Elsevier.
