Library Journal’s Library Hotline’s survey:

• 50% of all library users go on to buy books by an author they were first introduced to at the library;
• 20% of library users are “power patrons.” They visit the library at least once a week, borrow all types of media, and are active buyers of books and other media, including e-books;
• Power patrons are more likely to vote at a higher rate than other patrons; and,
• Power patrons are “influencers” who spread the word about books, visit both online and brick and mortar bookstores, and are more likely to purchase specific books they’ve borrowed from the library.
