Well gentlemen, all wise responses that give me plenty to think about. I am definitely sticking with the veneer Dave, I bought a 4' X 8' piece made to my specs and l have no other use for it. As to my current thoughts, here goes;
Regarding contact cement; first - I'm afraid of the fact that once it touches down, "you pretty much have to go forward." as Lazyman says, and I know from my experiences I'll never touch down where intended. Second - the smell is a killer. I helped a neighbor once years ago, who needed me to attach via a lap joint two sections of quarter inch ply for his new bay window sill, using his wood & his glue. I understand now why he wanted it done in my garage, my wife complained about the odor for a week.
Dave and Lazyman, you both mentioned using thin strips on a large surface, and I think you guys are on to something. The veneer I have was peeled from one cherry log that resulted in a repeating pattern of what looks like vertical boards side jointed, and as Lazyman suggests, I can cut it in strips with a razor knife. It's only about an eighth inch thick, and cut straight or not, the strips will match when assembled in the same order. I'll try to pick a section that looks like a board joint, and I'll need some working time for realignmen, so I guess it's just a matter of glue selection.
Thank you Dave, Lazyman, and Bentlyj, I'll post the bookcase project with the veneer details included. Right now, I'm finishing the molding trim, have time to think about glue.
