There are over 32,000 libraries in the United States. Libraries could be 32,000 local outlets introducing e-books to readers.
Libraries can circulate the current e-book technology.
Unfortunately, with the current technology, librarians can offer little more than a choice between reading on paper and reading on a computer screen. When presented this choice, most patrons and librarians select paper books. Imagine, for example, a patron asking a librarian for a book not owned by the local library. This choice gives librarians and patrons who never think of asking for an e-book a reason to do so. This capability may be necessary for circulating numerous e-books because few libraries can afford buying readers for all patrons.
