Dalhousie's WorldCat Local had problems with the FRBR implementation and they want some changes made to suit academic libraries. For example, if there are multiple editions grouped together, it shows at the top the one with the most holdings in WorldCat libraries. They always want the most recent edition to show, especially in the sciences.
Bess Sadler showed some great GIS stuff.
My York University colleague Ali Sadaqain talked about our implementation of VuFind.
