TO THE FIRST ITALIAN EDITION
Almost all the writings which compose the present treatise were printed in the proceedings of Italian academies and in Italian reviews between 1912 and 1913. Since they formed part of a general scheme, their collection in book form presented no difficulties. This volume has appeared in German under the title Zur Theorie und Geschichte der Historiographie (Tübingen, Mohr, 1915).
On publishing in book form in Italian, I made a few slight alterations here and there and added three brief essays, placed as an appendix to the first part.
