Where is the Reference Section?
Pius Library no longer has one single Reference Section; instead, all the reference books can be found on the same floor as the call numbers in the circulating collection (see the location guide here: http://lib.slu.edu/research/guide/location).
In the main Pius Library building, the Reference Section is on the southeast side of each floor. In the Lewis Annex, the reference books are all located on the fourth floor, to the right as you enter the main book stacks area of Lewis Annex.
Look in the Reference Sections around the library for basic research materials ranging from encyclopedias and dictionaries to extensive bibliographies and almanacs.
