We’re excited about Erik Hazzard’s new book on OpenLayers. We also wanted to promote Till Adams and Marc Jansen’s German OpenLayers book. Both are now featured on the OpenLayers homepage: http://openlayers.org/
In addition, I’ve added a small donation button at the bottom of the page. Financial contributions to OpenLayers support both the OSGeo foundation and our project. Any size donations are welcome – if we get enough of a pool, perhaps we can have a documentation sprint and give the OpenLayers docs (and website) a much needed overhaul.
