(POD) would allow libraries to change their collection strategies: they could buy and print a physical copy of a book only if a user requested it. When the user was done with the book, it would be shelved. It’s a vision of “doing libraries ‘just in time’ rather than ‘just in case,’” says Palfrey. (At the Harvard Book Store on Massachusetts Avenue, a POD machine dubbed Paige M. Gutenborg is already in use. Find something you like in Google’s database of public-domain books—perhaps one provided by Harvard—and for $8 you can own a copy, printed and bound before your wondering eyes in minutes. Clear Plexiglas allows patrons to watch the process—hot glue, guillotine-like trimming blades, and all—until the book is ejected, like a gumball, from a chute at the bottom.)
