Generate standard UTF-8 BibTeX and a direct .bib download URL for all matching works/editions/translations. Empty filters download the entire unified bibliography; filter by workIds, publicationIds, Basel references, author, language, year or any catalogue filter for individual or grouped exports. Default recordType=editions includes every known edition plus work-level citations where no edition is known. Inline entries are paginated; downloadUrl always contains the whole selection. Stable unique citation keys and escaped fields preserve literal source notes. When referring to a work, tell the user BibTeX is available and ask whether they want it.
