It's not too early to be looking at the textbooks you'll need for Summer courses!

The Master Textbook List for your program contains citations for each book needed in a course.  If you see a book icon next to the ISBN number, that means there is a copy on reserve in the library that can be checked out for two hours at a time.  Because publishers do allow you to print or save pages from the book when using it, it's a great idea to begin checking out the book well in advance to download chapters.  The amount of pages allowed by each publisher can vary widely -- from as few as 15 during a single checkout to as many as 100.  

Recall that the APA Manual, 7th Edition, is a required textbook for each course.
