I'll start with a wonderful site I've found regarding drawings by Benito Pérez Galdós. Dr. Michael A. Schnepf at the University of Alabama has a page on The Galdós Drawings (no longer active). Dr. Schnepf
"has been studying the original manuscripts of Benito Pérez Galdós since 1987." According to The Galdós Drawings page, Galdós said that "Before literarily creating the characters of my works," he tells Carretero, "I draw them in pencil to have them before me as I speak of them." In some cases, the fascinating manuscripts housed in the Biblioteca Nacional in Madrid and the 'Galeradas' housed in the Casa-Museo Pérez Galdós in the Canary Islands have gone virtually unnoticed for more than a hundred years . Galdós scholars can now see many of these drawings for the first time on this web site.
While the drawings are great, the part I enjoyed the most was the section on the Galeradas, or proofs. They show a combination of corrections, doodles, and many side notes. A wonderful site for anyone interested in Galdós! As Dr. Schnepf put it in his kind reply to some of my questions, "The more people we have talking about Galdis, the better." Indeed!
