Every line holds a rank, the title, the author, the Gutenberg number, the download count and the EPUB address, so an agent can copy one line without reading the rest."},{"q":"Is a book in this list free everywhere?","a":"No. The flag comes from Project Gutenberg and covers the United States only. Many authors on the list died long ago, which often settles the matter abroad, but the catalogue does not claim it and an agent should not either."},{"q":"Does the order reflect quality?","a":"It reflects readers' downloads only. A seldom-fetched novel can be better than the one in first place; the number measures how often Project Gutenberg's pages were used, not how good the story is."},{"q":"Are the sea and jungle stories complete texts?","a":"Each address points to the full public edition kept by Project Gutenberg, but the file itself holds no text. Abridged, illustrated or serial editions may exist under other numbers that were not listed. Maps, plates and engravings from the title pages are not part of what the file promises."}],"examples":[{"lang":"en","model":"claude-sonnet-5-5","input_excerpt":"Which book is number 1 in the catalog?","output_excerpt":"Number 1 in the catalog is **Moby Dick; Or, The Whale** by Herman Melville (Gutenberg #2701, 165,720 downloads).\n\nEPUB: https://www.gutenberg.org/ebooks/2701.epub3.images\n\nThe link answered with an EPUB file when checked on 2026-10-28.
