In respect to Common Lisp, you could look into "Common Lisp Recipes" by Weitz[2], and "Practical Common Lisp" by Seibel[1]. These are industrial-strength systems which were used to built large airline reservation systems.

Scheme is in a way more minimalist and Schemes are not as large, but this might also be give an erroneous impression because they build on the enormous experience with Common Lisp and have boiled down to the most essential parts - it is not the kind of minimalism "the simplest things that could work" but "what turned out to be indispensable in practice", which is a very different thing.
