aggregate_catalogGroup distinct works by up to two dimensions.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Group distinct works by up to two dimensions. Results are paginated. Edition dimensions refer to matching editions; counts must not be summed across overlapping groups.

  What this check looks for
Description, as the server wrote it
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.
