The workshop will be in Swirbul Library, towards the northwestern corner of camps (building SWL on the campus map). My office is room 203 Post Hall (building PSH, south-center of campus). All of this is on the main campus of Adelphi University, Garden City, NY.
See other maps, directions, and visitor information here. If you're coming by public transit, you may need the schedule for Adelphi's free shuttle bus (which runs to several nearby train and bus stations).
