Faithful and Scalable MARCXML Parsing R package marcxmlr version 0.2.1 Parses Machine-Readable Cataloging ('MARC 21') XML <https://www.loc.gov/standards/marcxml/> into a canonical tidy long representation while preserving leaders, control fields, data fields, indicators, repeated fields, repeated subfields, and source order. Provides an in-memory reader for manageable catalogues and a bounded-memory converter that writes larger collections as 'Parquet' datasets, with optional local parallel processing.
