how can i find what books for a class i have signed up for for instance my class is PSC-480-01 (31679)
Currently the bookstore system is unavailable. You should ask your instructor about the required books, or check your syllabus if you already have one. Once you do that, you can check the library's Course Reserve catalog here: http://arthur.searchmobius.org/search/j
Search by your instructor's name or the class number (in your case, PSC 480) and see if we have any books on reserve for that class.
