Textbooks and commentaries
Discrimination and worker's rights will, of course, usually be a chapter (or two) in general works on employment law shelved from KN190.
Warning! The looseleaf service Discrimination law shelved at KN191.2 may not be uptodate: check the front pages of the first binder to see when last filed and to see if it is missing any services.

Works on the philosophical basis may be in the wing, with a shelf mark beginning Jurisp.
