Source data

How was the data generated?

  • A crawler (see Open-Assistant repository) downloaded the raw HTML code for each eBook based on Text# id in the Gutenberg catalogue (if available)
  • The metadata and the body of text are not clearly separated so an additional parser attempts to split them, then remove transcriber's notes and e-book related information from the body of text (text clearly marked as copyrighted or malformed was skipped and not collected)
  • The body of cleaned TEXT as well as the catalogue METADATA is then saved as a parquet file, with all columns being strings

Copyright notice:

  • Some of the books are copyrighted! The crawler ignored all books with an english copyright header by utilizing a regex expression, but make sure to check out the metadata for each book manually to ensure they are okay to use in your country! More information on copyright: and
