 The collection was compiled by Pierre-Carl Langlais based on the [dumps](https://chroniclingamerica.loc.gov/data/ocr/) made available by the Library of Congress. Each parquet file matches one of the 2618 original dump files, including their code name. It has the full text of a few thousand selected at random and a few core metadatas (edition id, date, word counts…). The metadata can be easily expanded thanks to the LOC APIs and other data services.
