Hi Sneaks,
as you know most books specifically state that nothing out of it should be photocopied, distributed etc. unless one has the written permission of the publisher. I think if your presentation is in a small circle, it probably is not that much of an issue. If it is at a big conference, it could get you into trouble. Obviously the risk is low, yet if I were you I would not do it. Maybe better just to say that your presentation is based on this and this book and just provide the audience, if interested, with the reference.
