"Digital collections marketing is an important, yet often ignored aspect of digital collection management. While many collections are laudable for the quality of their pictures, metadata, and preservation techniques, they often remain obscure, unknown, and therefore inaccessible to their intended user populations. One of the ways digital librarians can cultivate a broader awareness of their collections is through social networking."
Most libraries have Facebook pages. They’re great for putting up hours and events and highlighting your collections, but unless you put in some special effort, every Facebook page looks more or less the same.
