Another book in the collection is " Historia Universal de la Infamia" (A Universal History of Infamy) which is a brilliant research about several Infamous characters like Billy the Kid and Hakim of Merv (the veiled prophet), a character which will again show up in several of his tales. A History of Eternety also gets loads of more material for his tales, Thousand and one nights stuff, Icelandic Edda etc.
The rest of the book is composed by Ficciones (Fictions) and the Aleph. These fantastic tales, are amazing. He uses and abuses going beyond the story, plenty of reviews of non-existing books, tales told as truth by Borges, as autobiographical about non-existing people, references to non-existing authors, tributes to non-existing writers etc.. Just fuckin read it.
Next up: The Idiot by Dostoyevsky and Jorge Luis Borges - Obras Completas Volume II 1952- 1972
