Dean of the Library

Sonoma State University

I am the Dean of the Library at Sonoma State University, an august entity that disavows everything written on this blog and through the wriggling of eyebrows hints around that perhaps I could be doing something better with my time like running a university library, yo. I was formerly the University Librarian at Holy names University in Oakland, California (a place that seems remarkably similar to the 'Cupcake U' I sometimes blogged about).

The Evergreen Project was initiated by the Georgia Public Library System in 2006 to serve their need for a scalable catalog shared by (as of now) more than 275 public libraries in the state of Georgia. After Evergreen was released, it has since been adopted by a number of library consortia in the US and Canada as well as various individual libraries, and has started being adopted by libraries outside of North America. The Evergreen development community is still growing, with about eleven active committers and roughly 65 individuals who have contributed patches (as of March 3, 2013). However, the Evergreen community is also marked by a high degree of participation by the librarians who use the software and contribute documentation, bug reports, and organizational energy. As such, Evergreen is very much about both the developers *and* the users.
