|Many lecture room numbers are of the form letter + digits, e.g. H 051. The letter indicates the building and the first digit the floor, with 0 standing for the ground floor, so that H 051 is on the ground floor of Humanities (which is 24 on the map). There are some exceptions to this rule detailed below the map.
LIB 1 is on the ground floor and LIB 2 on the first floor at the Library bridge level.
