In case anyone’s interested, Realm of Racket, an introductory text coauthored by the author of Land of Lisp, is free to borrow at Realm of Racket by Forrest Bice | Open Library
If anyone’s interested in Land of Lisp itself for learning Common Lisp, it’s not in Open Library, but it can be borrowed from the Internet Archive at Land of Lisp : learn to program in Lisp, one game at a time! : Barski, Conrad : Free Download, Borrow, and Streaming : Internet Archive.
