Our library partner, the San Jose Public Library, offers a service called Discover and Go that allows you to download and print free or discount passes to several bay area museums, including the San Jose Museum of Art. You will need to log in to this service with your SJPL library card number and PIN. There are a reserved number of tickets available per day, so be sure to log in to the service before the day you wish to go to a venue.
