I don't know what my library is anymore. Personalizing library sites is here to stay, and the July Library Journal points out several efforts whose authors are "willing to share their code": My Library at Virginia Commonwealth University [1], MyLibrary at NCSU [2], and My Gateway at University of Washington [3]. More than just a perfect marketing pitch to the American consumer, no? :)
