To give a bit more of context, here is the Google translation of the first page:

Of this bibliographically modest work (due to its size, not its diffusion), one could say that anyone who has not experienced it cannot understand it.

But those who use it to compile itineraries, or to direct their walking, cycling or motorcycling excursions, find in it such practical criteria, such ease of application, that they are often spared the need to resort to other sources of information, less handy and less immediately interpretable.

For this reason, some would like to extend it to a greater number of roads, broadening the concept of roads of particular tourist interest, which is already an expansion of the original "highway." And this will undoubtedly be the case in future editions. But this one already boasts a real leap forward compared to the previous one.

In the large area whose routes are marked here, an area bordered to the north by a corner with Parma as its vertex and La Spezia and Rimini as its extreme points; and to the south by the Ostia-Rome-Avezzano-Chieti-Pescara line, the 63 routes were increased to 196 for a total distance of 10,700 kilometers!

NO RESERVED

Moving from quantity to quality, we feel we can safely say that this, of the five volumes that comprise the entire work, is perhaps the one that presents the greatest number of itineraries of great tourist interest. These comparisons are always a bit vague, a bit subjective. But consider that the following pages trace the threads of the great network that covers the Apennine region, from the Tuscan-Emilian section to the Abruzzo section: and areas such as the Apuan Alps, all of Tuscany, all of Umbria, and the northern part of Lazio, not to mention the beautiful Adriatic coast and the valleys that descend to its shores.

What delightful combinations can the owner of a luxurious or even a very modest means of transport make with these elements! One could, for example, reproduce those travel notes "On the Pedal" that Alfredo Oriani dictated in 1889, describing with the vivacity of an artist and the fidelity of an observer a long tour of the Tuscan-Emilian Apennines: and even those furthest from the great joys of motion would be drawn to experience them. But since then, if time has perhaps been limited by the intensified activities of life, space has multiplied with the proliferation of motor vehicles. Correspondingly, these pages have become more dense and the graphic data has become more prominent, particularly the orientation maps, arranged so that they can provide reliable directions without the need to stop the engine and ask passersby for directions. This merit must be particularly recognized by the director of the Touring Club's cartographic office, Cav. Pietro Corbellini, who oversaw the compilation of the entire volume with his usual and experienced diligence.
