title: 'abstractExtractR: Retrieve and Audit Scholarly Metadata from Multiple Sources'
version: 0.3.0
abstract: Retrieves and normalizes scholarly article metadata and abstracts from the
  'Crossref' REST API <https://www.crossref.org/documentation/retrieve-metadata/rest-api/>,
  the 'OpenAlex' API <https://help.openalex.org/> and the 'Scopus' Search API <https://dev.elsevier.com/sc_apis.html>.
  Provides bibliographic searches, cursor pagination, publication date and author
  filtering, abstract retrieval by Digital Object Identifier (DOI), cached batch enrichment,
  merging of duplicate records, metadata-quality audits, reproducible search snapshots,
  local archives with integrity verification, and export to comma-separated values
  (CSV), 'BibTeX' and 'RIS' citation files. Network requests support configurable
  timeouts and test callbacks. 'Scopus' searches require an 'Elsevier' API key; 'Crossref'
  queries do not. 'OpenAlex' supports limited keyless searches and authenticated pagination.
