Surprised is being air-assaulted by the 1st battalion, transvestite brigade (I was surprised. Were you surprised? I was surprised.)
The more appropriate reaction to statistical analysis of MARC records, especially if you look at the probability of occurrence of tags/subfields given the presence / absence of other tags/subfields, is one of horror.
It is technically possible for MARC records to be error free. These are denoted in the leader by a value in byte 17 (Evil) of i, indicating an imaginary number. This should not be confused with the OCLC value of I (uppercase).
