Where the land's books are now

SUMMARYWhere the land's books are now (agent report, Nov 6, 2026; follows P817). Dataset books_of_the_land.csv (32 codices and 9 khipu holdings); report agent-reports/books-of-the-land.md. Many rows rest on Wikipedia, so check the institutions' catalogs before print. BY COUNTRY: UK 7, France 6, Mexico 6, Austria 3, Vatican City 3, Italy 3, Spain 2, Germany 1, unknown 1. PRE-CONTACT BOOKS: 15 clear, of which 13 are in Europe and 2 in the Americas (the Maya Codex of Mexico, ex-Grolier, and the Mixtec Codex Colombino). HOW THEY LEFT: mostly unrecorded; most first appear already owned by European collectors between 1596 and 1832. Named routes: Vindobonensis I, Cortés to Charles V (1519), reaching Emperor Leopold I (1677); Mendoza, French privateers per Purchas (1625), Disputed because it is secondhand. RETURNED, five: Boturini (taken to London by Bullock 1824; how it came back is unknown), the Maya Codex of Mexico (seized under a US–Mexico treaty, 1976), the Cruz-Badiano herbal (returned by Pope John Paul II, 1990), Chimalpahin (bought back at Christie's, 2014), and the Aubin Tonalamatl (taken from Paris in 1982 by José Luis Castañeda del Valle and kept by Mexico; legal status disputed). No European holder has given back a pre-contact book; France has kept the Borbonicus in the country since the 1960s. KHIPU: about 1,400 survive; the largest single collection, about 298, is in Berlin's Ethnologisches Museum (count Disputed, uncited). BURNINGS: Itzcoatl (single post-contact source, Record); Zumárraga (Disputed: Kingsborough and Prescott accuse, García Icazbalceta rebuts, León-Portilla holds that he did order burnings); Landa at Maní (the counts of 27 books and 5,000 images Disputed); the Third Council of Lima (1583) ordered khipus burned (Record, no count)
