I used to be a directory assistance operator years and years ago...before computers...when a real person actually answered your 411 call. Anyway we had books...with new listings being added everyday..the books had to be updated and replaced a lot. The 3 holed loose pages were attached to a metal spine which hooked onto a big metal stand that stood at an angle and then all these books stood open and we would just sit there and literally thumb through them for phone numbers. I never forgot those things...and when everything went to computers, I wondered whatever happened to those things...they were used by operators all over the country...NOW I KNOW!! Those scrapracks are exactly like what the DA operators used. ..EXACTLY. They sound like a good idea. I have no room for one..they can get big.
