In that little system [= ein kleines Katalogisierungs-Tool, das der Verfasser 1970 gemeinsam mit IBM Dänemark entwickelt hatte] all keying was done in upper case. In the computer it was converted to lower case – and through an algorithm the appropriate letters were again changed to upper case. A computer person once said to me: That habit of yours with upper and lower case letters, isn’t it just a bads habit? Why don’t you just leave it? My answer was: It may be a bad habit, but it is rather common, so we will like to stick to it.
It was that kind of silly questions librarians got in those days.“
