Quite a random selection for such an official looking URL; what about e.g. "Common Lisp - The Language" (https://www.amazon.com/-/de/dp/1555580416) or e.g. "Object-oriented programming in Common LISP" (https://www.amazon.com/-/de/dp/0201175894)? However, the reference to "Principles of Biomedical Informatics" was useful; looks like a very interesting book; another important CL application book not on the list, is of course "Paradigms of Artificial Intelligence Programming" (https://www.amazon.com/-/de/dp/1558601910).
CLtL2 ( https://www.cs.cmu.edu/Groups/AI/html/cltl/cltl2.html ) is freely available, PAIP ( https://github.com/norvig/paip-lisp ) also .
