ALA Outstanding Books for the College Bound
From the ALA site:
A YALSA Committee of public, secondary school, and academic librarians selectes the list. Revised every five years as a tool for several audiences (students preparing for college, educators, librarians, and parents) it offers opportunities for independent reading and lifelong learning. Use it to round out your reading as you prepare for college entrance exams and courses, to strengthen your knowledge in a variety of subject areas and enhance appreciation for different cultures and times.
