In the book Fahrenheit 451 do you have a sense that there are other "book chapters" in other towns? What proof do you have?I'd like my question...

There are definitely other book chapters in other towns. 
When Granger is explaining their system of memorizing books, Montag asks him how many of
people are involved in this endeavor. Granger explains that there are thousands on the
roads and the abandoned railways. They look like bums on the outside, but they are
libraries on the inside.  He tells Montag that over a period of 20 years, they have
developed a "network". (pg 153)  He says that some of them live in small towns and tells
of a town in Maryland in which 27 people have memorized the complete works of Bertrand
Russell. Everyone is quietly waiting for the day when they can rewrite the books, but
until then they will pass on their knowledge through their
children.
