I am assuming that if the books were the size of the Kelly Blue books (as I remember them) with bounded soft covers which one could leaf through with one hand, it would be easy. They could be carried around in one's pocket freeing a persons hands for other usage.

As it is now, one must carry the book either under his arm, in a carry case or even in his hand, which can become quite heavy if toted long enough. In any case Michael, How long do you think it is going to take before the book becomes too cumbersome.

With thanx from all of us, you are adding more and more vital information for us collectors, but we must have a way to access it.
