Yet another case of duplicate publication

A paper published in journal A in 1990 was published almost verbatim in journal B the following year, and yet again in journal C in 1993. None of these publications made any reference to the others. The case emerged in the process of one of the authors applying for a professorship. The authors conceded their error when tackled on the issue. One editor agreed to publish notice of duplicate publication, but difficulties were experienced tracking down the third editor.
