Well, here's the main points; the first film was based on the first novel. Then after the first film's major success, author Michael Crichton decided to write a sequel to his first novel. He also made a major point in stressing that the sequel movie that would undoubtedly follow would be different from his book (inspired in some ways, but in truth Steven Spielberg's film). So I guess you could stress that the first and second movie's were based on the book duology, but the third movie uses some elements from the novels as well.
