Reference librarians are trained to sift through reams of information and locate data in a way that Google can’t, and harnessing these human resources is the aim of the Text a Librarian mobile reference service, which is now used in more than 800 libraries around the country. Participating libraries advertise a phone number to which patrons can text questions during library hours and get answers from librarians; apart from standard text messaging rates, the service is free for users. The Topeka & Shawnee County Public Library is likewise using its website to let users ask questions during live-chats with a librarian. Contra Costa County Library in California has launched a Snap and Go campaign that enables smartphone users to snap a QR code from a library poster they see around town and download an audiobook without having to step foot in the library. And at least one library is experimenting with recommendation engines. The Gimme! mobile app developed by Arizona’s Scottsdale Public Library is powered by staffers’ recommendations as well as data from the library catalog to provide personalized suggestions of good books to check out, as a hyperlocal alternative to Amazon.
