I was cleaning out stuff from my parents' house and found a bunch of college admission crud from 1981. Funniest was a postcard I was apparently supposed to write my name, height and weight on and then mail to Yale.
Remember how every application was different and needed different essays and things? Nowadays it's one common application (My kid did it a couple of years ago).
The old system was self-limiting in the number of schools you could reasonably apply to but now you can apply to as many schools as you have the application fees for.
