You no longer need to present this classic. Having had written in collaboration with Kubrick, the book and the movie are very close. As for the book, I really appreciated that the author goes into detail technical and Astronautical. In fact, 2001 is placed between the SF novel and the work of science. All this, of course, carried by a style Asimov: pleasant, efficient, powerful and yet very descriptive. This edition has an interesting recent preface the author (1999 - the book dates from 1968) which chronicles the creation of the work and the privileged link entertained by AC Clarke and S. Kubrick.
