Colporteurs and book peddlers

Colportage is the distribution of publications, books, religious
 tracts by carriers called 'colporteurs'. The term does not necessarily 
refer to religious book peddling. Book peddlers were travelling vendors 
of books. Door-to-door book peddlers of the 18th and 19th centuries, 
also known as 'book canvassers', used to carry special 'sample books', 
a kind of "preview", with table of contents, sample illustrations and 
some text, designed to advertise the book in question
