Do I need to buy all book titles listed for my courses?

Answer: 

Not necessarily. Check the tags on the textbook shelves to distinguish between titles that are required and those that are listed as optional. A careful review of the course syllabus can also help you determine the extent of the reading assigned or when a book will be used during the course. Some syllabi are available online prior to the first class.
