For the past several years (since 2008), the Colorado State Library's Director of Library Development and Innovation, Sharon Morris, has given a talk at the annual Colorado Association of Libraries conference about library trends. She has a sharp eye, and I find that the things she picks are the things to watch. I'm pleased to report that she's put up a site, here, where she briefly summarizes her observations. She also, from time to time, posts her thoughts about various issues. Highly recommended.
