Giuseppe Pitrè (21 December 1841 – 10 April 1916) was a Sicilian folklorist who compiled the Biblioteca delle tradizioni popolari siciliane (Library of Sicilian Popular Traditions), a twenty-five-volume collection of Sicilian oral traditions. The collection is available for free online via the Internet Archive. However, the archive does not label these files with volume number or title. I have done so for your convenience:
