In my effort to read more classical and prize winning books, I have utilized two lists to help me accomplish this task. Not to mention, I LOVE making lists and crossing things off. Hope these can help you to find new reads!
The 1st list is the 100 Best Books of all times according to The Guardian.
The 2nd list consists of all the Pulitzer Prize winning books from 1917 to present.
Let me know if there is another good list you use.
