Further in there is project Guttenburg - where they will publish two books a month!
I clicked on the 1991 list of books. It was taking too long. They must still be on dial-up. Back in college (1982) we thought it was great to have the gizmo where we could put the handset of the telephone in it and get a connection to our work on the school’s mainframe. (It sure beat having to use the punch cards that we first learned on!)
