Wow, a lot of great replies and good ideas. Some additional info..
1) He does have the run of the house except we keep the bedrooms and bathrooms closed when we aren't there. And if we are diligent, we don't normally leave books and shoes out where he can get them. But with a librarian in the house, you can imagine how many books we have and they are all targets. The good news is that if a book is on a bookshelf he wont go after it. If not, the book is toast.
2) Walking in the morning is hard for us because of our schedules. With two school age kids and two working parents, we are barely able to get ourselves sorted out, much less the dog. We are pretty good about exercising him in the evening though
3) interestingly enough mudpuppy, our dog by himself has decided to only chew in one place. Go figure! [

4) we have tried Kong's for the longest time, and he's just not interested. To chew on we give him these beef tendons and most of the time that will keep him busy for an hour or so, but some days he just doesn't like them
5) DPU we did hire a personal trainer to help us train our dog, and that helped a great deal. I hadn't had a dog since 1975, so I didn't think I knew what to do to train him. so it was money well spent.
6) Does anyone think it might be a good idea to set a trap for him? Meaning, leave a book out while we are home and catch him in the act so we can correct his behavior?
And once I get a handle on this, I'll need help on getting him to walk on a leash! Toy Spaniels evidently have a hard time with walking nicely on a leash, and boy is that true. But that's for another thread...[
