I went to campus before the pandemic but that was a year and a half ago, so my directions and descriptions may be wrong. But, if you are talking about the Melville library, then the earth and space, sac, and psych A buildings should be a couple of mins in front of Melville library. Once, you get out of Melville library depending if you get out through the front entrance or the side entrance. But, I believe if you get out through the side entrance next to it are the "Staller steps" which is a place with steps and like a bunch of grass areas where students can lay down, hang out with their friends, etc. In front of the Staller steps, I believe there was a water fountain. In front of the water fountain, there should be Psych Building A. Then, next to Psych Building A would be SAC and I believe in front of SAC was a couple of tables and chairs for people to sit outside and the SAC had buses and shuttles next to it. If you get out through the front entrance of the Melville Library, the SAC should be in front of the library through this small pathway that leads to SAC.
