Scheme has an edge for education in computer science (which has different goals than teaching you actual Lisp programming) over Common Lisp, because there are some good books and courses based on Scheme.

For learning Lisp programming, Common Lisp has also extremely good books. Both basic, mid-level and advanced.

Examples:

Touretzky, Common Lisp: A Gentle Introduction to Symbolic Computation

Barsky, Land of Lisp

Graham, ANSI Common Lisp

Graham, On Lisp

Winston/Horn, Lisp

Seibel, Practical Common Lisp

Weitz, Common Lisp Recipes

Norvig, Paradigms of Artificial Intelligence Programming, Case Studies in Common Lisp

I would recommend each of these books to people who want to learn Lisp programming or certain aspects of it.
