The Biblioteca Universale Sacro-Profana is an unfinished encyclopedia from the early 18th century, published in Italian by Vincenzo Coronelli.[1][2] It is said to be one of the first universal encyclopedias with entries arranged alphabetically. It was planned to contain 45 volumes, but only 7 volumes appeared, reaching the letter "C".
Biblioteca universale is a bibliophilic rarity today. Few European libraries have the complete set of volumes. In Poland, for example, the only copy is in the Library of the National Institute in Wroclaw and even that is incomplete, containing only volumes 1 to 5.
