I hope we will use the A* family of paper sizes in the USA more widely. Many excellent notebooks, notepads, &c are available from Germany, Japan, France and England in the A* family of sizes, and they all work with the corresponding envelopes. There is so much paper correspondence -- in the form of utility bills, government notices, packing lists, and many other things -- that could fit on A5, which is a handy size for many things; and now manufactured in great quantities all over the world.
