On examing the map again, you see that the passage to your left leads to various computer labs and connects to another long passage which goes past the Science Library and connects to a confusing maze of stairs and other passages next to the Chemistry Building. Behind you is the undercroft of the Maths/Physics building. The passage to your right leads to a maze of offices, all alike. Your best chance of finding Peter's home page is probably to the right.
