Until about twenty years ago, libraries could conceivably be cut off from other libraries. Although mostly connected to the American Library Association, your typical public, academic, or school librarian could run a stable ship with a minimum of communication with other librarians.
Not anymore. Economic considerations, the burgeoning pace of technology... all of which forces libraries and librarians to work together far more than before. Many school librarian bloggers discuss technology literacy, and given the wide range of technology, it's hard to keep up with the various wares that pop up seemingly every week.
The E-Literate Librarian is the brainchild of Tamara Cox, a South Carolina-based middle school librarian. She concentrates on promoting literacy, particularly technology literacy, amongst her students. She writes not from the perspective of a techonlogy expert but of a novice, writing as she learns. This makes the blog a more friendly, more comfortable place to learn about school librarians and technology.
Even more tech-heavy, but more from the perspective of an expert, is The Daring Librarian. Also a middle-school librarian, she is a self-admitted geek, pushing technological literacy with her students, such as creating audio QR codes. She writes with the enthusiasm of a true believer, and for that reason she is the go-to gal for school librarians pushing technology.
