 Several of the entries matched copies of books, now missing their maps, which Smiley had examined.For example, Smiley had admitted stealing from Harvard University an example of the map of the Aztec capital Tenochtitlan, illustrating a letter from Hernán Cortés (1524), but a prior photograph of the example missing from Yale's Beinecke Library proved instead that it was theirs.Several questions remain unanswered, in particular about the origin and purpose of high quality facsimiles of early maps, some found on Smiley's person when he was arrested, and others in books he examined.
