%%%                        Data for this bibliography have been derived

%%%                        Sadly, there are at least seven instances of

%%%                        page numbers are incorrect.
%%%
%%%                        There were also 38 articles in the publisher
%%%                        metadata where starting page numbers were

%%%                        Numerous errors in the publisher metadata
%%%                        sources noted above have been corrected.
%%%                        Spelling has been verified with the UNIX

%%%                        BibTeX citation tags are uniformly chosen
%%%                        as name:year:abbrev, where name is the
%%%                        family name of the first author or editor,
%%%                        year is a 4-digit number, and abbrev is a
%%%                        3-letter condensation of important title
%%%                        words. Citation tags were automatically
