Work with PG catalog files
Project Gutenberg makes several catalog files available on its website. They are free for all to use.
All Project Gutenberg metadata are available digitally in the XML/RDF format. RDF files are updated daily. You may find code in the "Gitenberg-dev" repo useful for reading these.
A CSV file zipped is compatible with Microsoft Excel. Note that titles with subtitles in the CSV file may span multiple lines. The process_csv.py script in this repo can be used to turn the titles onto single line titles. You can modify the script if you want to put subtitles into a separate column.
The MARC file available for download at PG should not be used, as it is 7 years old. A new MARC file generator is on the development roadmap.
