A friend has put together two self-published books on some things he did in Africa. They are very nicely done with great color photos. I think they were soft cover however. Not super cheap but I can't quote prices.

One thing about CD's - 50 yrs from now CD readers will be extinct. 5 yrs from now they may be endangered. A plain ol' book will always be readable if it is reasonably taken care of. Think long term, and go paper. It is still the only real archival medium.
