Passport requests [Municipal Archives]

In some municipal archives there are records of passport requests. Our ancestors had to have a passport to leave Italy, not necessarily to enter other countries (it depended on the country and period), and they applied for it to the police.
This post is to show you what genealogical informations can be found in these registers, and some examples of interesting cases.
In this archive the first register goes from 1908 to 1916 (1917) and it has yearly indexes, the second register is for 1919-1938 and mostly doesn't, so it must be checked page by page: the entries are chronological (and divided by year) and not alphabetical.
I've noticed that initially most requests were for Germany and France, then after a few years Buenos Aires (Argentina) and Canada became the first destinations. I'm sure this is different in other towns/provinces. As we know, most southern Italians chose the United States, while in the north Canada and South America were more popular.
As usual these are big books and the registrations span the 2 sides:

Column headers:
- Progressive number
- Date of request
- Surname and Name of applicant or of those accompanying them
- Father's name
- Place of birth
- Date of birth
- Occupation

Column Headers (page 2)
- Country for which the passport is issued [sometimes a city/port]
- Surname and name of the person giving consent where required by the Royal Decree (31st of January 1901, article 3, number 2)*
- Authority to which the autorization is transmitted
- Date of transmission
- Passport delivery date
- Passport number
- various annotations

Sometimes you find families together: minors were usually added on their parent's passport, they did not have one only for themselves. Wives were added to the husband's, too, most of the time. As were younger brothers to their older brother's.
This is an example of a family, I've highlighted it in red and I've added more text to these pages explaining other things.

This next one is peculiar, because it notes 3 brothers leaving Italy clandestinely when their passport was refused.

Other reasons to leave could be tourism, visiting the family or an ill family member, a pilgrimage, etc.

There were periods during which dozens of people form the same area were recruited by agents and sent to work together for the same company abroad, and we can see that from the passport requests.
Here just 2 of the many pages I've seen, they were all listed as labourers and bricklayers:
