The Theka Caverni has been set up to make available to scholars, as well as others, an integrated archive of digital resources relating to Raffaello Caverni, an unusual person: a man of letters and a country parish priest, a pioneer as regards the nineteenth-century history of science, a passionate communicator and conciliatory evolutionist.  His achievements have remained on the margins of more recent studies, partly because his personal archive up to now has been inaccessible owing to its lack of structure.
