There were some pretty crazy markup errors in this tag soup, but generally
it wasn't difficult to repair. The following needs to be double-checked:

preface: Should "September 1978" be italicized?
ch12-5: Is "Boston Sunday Globe" correct?

More instances of broken <cite> tags also warrant investigation.
