  At the time of publication of H. Everett's Relative-State Formulation (1957)
and DeWitt's Many-Worlds Interpretation (1970), quantum mechanics was available
in a more modern and adequate version than the one used by these authors. We
show that with the more modern quantum theory, quantum measurement could have
been analyzed along more conventional lines in a one-world cosmology. Bell
criticized the Everett-DeWitt theory quite sharply in 1987 but this seems not
to have affected the acceptance of the old quantum mechanics as the framework
for analysis of measurement.
