Napulitano: Abruzzese songs, collection by Cesare De Titta (1862 – 1933), an italian poet in abruzzese that now is in the public domain in Italy.

This book: Canzoni Abruzzesi is the original version, published in 1919 in Lanciano.
This is my own scanning work, performed by simple mechanical scanning, and will be improved in order to provide track for the least visible lines.

Any doubt, do not hesitate to contact me.

One can argue that since the book was published in 1919 (<1923) and the author died more than 70 years ago, this book is also in the public domain in the US.
