The data file Project_Gutenberg_total_books.data is based on the website of Project Gutenberg.
- Records from 1 to 40,000 are derived from the Book Milestones (PG U.S.) section of Statistics (archived) on Project Gutenberg News.
- Later records are according to Release Dates of books by EBook-No. For example, John Gutenberg, No. 50,000, was released on 2015-09-17. The assumption can be verified by Project Gutenberg Releases eBook #50,000 (archived) on Project Gutenberg News.
