I have my book list expenses. I am not sure if I was required to buy them directly from my school or not. I always buy them from the school because it is easier.

Note below: depending on the type of credit you apply for there are different requirements.

These expenses qualify, as long as they are required to enroll in or attend a qualified educational institution:

• Tuition, if paid to the institution
• Student-activity fees, if paid to the institution
• Books, supplies, and equipment, if required to be purchased from the institution as a condition of enrollment or attendance (Lifetime Learning Credit)
• Books, supplies, and equipment, regardless of where purchased (American Opportunity Credit)

Fees paid for non-credit courses and sports (or similar activities) don't qualify unless:

• The course or activity is included in the student’s degree program, or
• The course helps the student acquire or improve job skills (Lifetime Learning Credit only)

These expenses are not considered qualified education expenses for either credit:

• Tutoring
• Housing, room and board
• Insurance, including student health fees
• Medical or dental expenses
• Transportation
• Entertainment, babysitting, and other personal expenses

Qualified education expenses paid on behalf of the student by someone other than the student (such as a relative), are treated as paid by the student. Qualified education expenses paid (or treated as paid) by a student who is claimed as a dependent on your tax return, are treated as paid by you.

If you are an undergrad, you will most likely be claiming the American Opportunity Credit, so it doesn't matter. 

You don't say whether the student or parent will be claiming the credit. Be advised that 

There's a new urban myth among college students that says they can get a $1000 from the government just for filing a tax form. For most of them, they simply aren't eligible. A full time unmarried student, under age 24, even if you don't qualify as a dependent, is only eligible for the refundable portion of the American Opportunity Credit if he supports himself by working. You cannot be supporting yourself on parental support, 529 plans or student loans & grants. You usually must have actually paid tuition, not had it paid by scholarships & grants.  It is usually best if the parent claims that credit. 

You cannot claim a credit if you are, or can be, claimed as a dependent by someone else.
