If you're pretty comfortable with your programming chops, want to get up and running quickly, or are planning to do "real-world" programming with Lisp, Practical Common Lisp (http://www.gigamonkeys.com/book/ http://www.gigamonkeys.com/book/) is great. Personally, I loved learning Scheme (a dialect of Lisp) from from Structure and Interpretation of Computer Programs (http://mitpress.mit.edu/sicp/ http://mitpress.mit.edu/sicp/), and since it's used to teach CS courses, you can find lots of exercises and project ideas online. If you don't mind a slower, more concept-based learning method, you can supplement your programming projects with this book.
