The document discusses research on U.S. public library users and their behaviors and preferences. It provides statistics on the size of the U.S. public library market with over 9,000 libraries and 169 million users. Known as "Power Patrons", frequent library users (weekly visits) tend to be middle-aged women with a college education. Power Patrons use libraries to borrow books, browse shelves, and search the catalog. The research also finds that library patrons purchase books, especially ones they previously borrowed, and consume content in print, ebook, and audiobook formats. Many patrons want more ebooks available from their public library.
