Many years ago (before you were born I’m sure) Hernando Colón, son of Christopher Columbus, collected many books from around the world–close to 15,000 tomes.
After amassing his collection, Colón employed a team of writers to read every book in the library and distill each into a little summary in Libro de los Epítomes, ranging from a couple of lines long for very short texts to about 30 pages for the complete works of Plato, which Wilson-Lee dubbed the “miracle of compression”.— Alison Flood, The Guardian
That summary, The Libro de los Epítomes, was picked up by the Icelandic scholar Árni Magnússon and donated with his collection to the University of Copenhagen in 1730. It has now been rediscovered for the gold mine into forgotten reading that it is and will be made digital next year, giving us good look into the printed material being read in those days.
