be consistent with journal/conference names. no need for publisher address unless it's someplace obscure, and no need for publisher if it's implicit in the conf/journal name (i.e. ieee/acm), and no need for the location of the conference. always doublecheck that the pages are in there (both the start and end page!). the only acceptable exceptions are when it really is an online-only venue where there are no explicit pages (examples include the BELIV workshop proceedings or the Foundations and Trends in Human–Computer Interaction journal).
also be concise and consistent: 'Trans.' not 'Transactions', 'Symp.' not 'Symposium', 'Conf.' not 'Conference'. don't include words like "of the" or "on". Don't ever say 'pages', just 'p.'
do include the accepted nickname/shortname for conferences in parentheses after the long name. don't include the year after that nickname, it's already communicated by the year that comes at the end of the citation.
example of bad bibliography snarfed off the web:
"M. Wattenberg. A note on space-filling visualizations and space-filling curves. In Proc. of the IEEE Symposium on Information Visualization (INFOVIS'05), volume 0, page 24, Los Alamitos, CA, USA, 2005. IEEE Computer Society."
"M. Wattenberg. A note on space-filling visualizations and space-filling curves. In Proc. IEEE Symp. Information Visualization (InfoVis), p 181-186, 2005"
if you're pressed for space, change long author lists to 'FirstAuthor et al'. I normally do full names for four or less, and switch to et al for five or more. The way to do this in latex/bibtex is "John Smith and others" for author list.
make sure that you've got the right capitalization in titles using curly braces around elements that should not be lowercased automatically. Main offenders are "D" (3D, ND), acronyms, and camelcase names.
in short: check your bibliography *very carefully*. do not be sloppy and inconsistent. be assured that i will notice.
in more detail from Ullman, on "Avoid non-referential this"
While it sounds pedantic at first, you get a huge increase in clarity by chasing the "nonreferential this" from students' writing. Many students (and others) use "this" to refer to a whole concept rather than a noun. For example: "If you turn the sproggle left, it will jam, and the glorp will not be able to move. This is why we foo the bar." Now the writer of this prose fully understands about sproggles and glorps, so they know whether we foo the bar because glorps do not move, or because the sproggle jammed. It is important for students to put themselves in the place of their readers, who may be a little shaky on how sproggles and glorps work, and need a more carefully written paragraph.
