Thanks for your warm welcome,and your good questions.But they seems to be a little bit sternly described,because i'm searching for more,if you understand me.So is there any book that would help me?
Don´t know what time era you are most interested in.
But Bill Bonanno´s new book (released two months ago) "the Last Testament" is a very interesting read about the old times.
Among other things, he describes the structure of a crime family as it once was.
And he should know. He was the son of Joseph Bonanno, the powerful New York boss who headed the Bonanno Family from 1931 to 1968. Bill funcioned as a soldier, captain and breifly as a consigliere in the 50s and 60s.
The book gives a great info on the foundation of the mafia you might find valuable and provides a stepping stone for further researching into the today´s mafia.
