OVERCITE.STY

Modify LaTeX's normal citation mechanism to:

o Display citations as superscript numbers, with a comma and a small space
  between each number, and with three or more consecutive numbers compressed
  into a range like 3-7.

o By default, sort citation numbers into ascending order; print non-numbers
  before numbers.  All numbers should be greater than zero.  (The [nosort]
  package option turns off sorting.)

o If an optional note is given, typeset the whole list of citations at regular
  size as if cite.sty was in effect.  (See cite.sty).

o Use THE SAME INPUT FORMAT as for ordinary citations; this style will ignore
  spaces before the citation, and move trailing punctuation to before the
  citation.  For example, "...information \cite{source};" ignores the space
  before \cite and puts the semicolon before the number, just as if you typed
  "...information;$^{12}$".

o The punctuation that will migrate before the superscript is .,;:.  Perhaps
  ! and ? should too, but they weren't listed in the APS style manual I looked
  at.  Quotes were listed, but they should never have to migrate because both
  on-line and superscript versions put quotes before the citation.  This gives
  one difficulty --- punctuation following quotes won't migrate inside the
  quotation.  For example,  "``Transition State Theory''\cite{Eyring}." gives
  "``Transition State Theory''.$^8$", but you may want the period inside the
  quotes, thus: ``Transition State Theory.''$^8$.

o Doubling of periods (.., ?., !.) is checked for and suppressed. The spacing
  after the citation is set according to the final punctuation mark moved.
  There is a problem with double periods after a capitalized abbreviation
  or directly after \@ : Both of "N.A.S.A. \cite{space}." and "et al.\@
  \cite{many}." will give doubled periods.  These can be fixed as follows:
  "N.A.S.A\@. \cite{space}." and "et al.\ \cite{many}.". These work properly
  for both cite.sty and overcite.sty, but the NASA example gives the wrong
  spacing when there is no citation.  Sorry.  Use \  after abbreviations like
  et al. to get the right spacing within a sentence whether or not a citation
  follows.

o All the special handling of punctuation can be disabled by specifying the
  [nomove] option.

o Define \citen to get just the numbers without the brackets or superscript
  and extra formatting.  Aliases are \citenum and \citeonline for easy
  conversion to other citation packages.

o `Citation...undefined' warnings are only given once per undefined citation
  tag.  In the text, missing numbers are represented with a bold `?' at the
  first occurrence, and with a normal `?' thenceforth.  The package option
  [verbose] restores the usual repeated warnings.

o Make \nocite, \cite, and \citen all ignore spaces in the input tags.

Although each \cite command sorts its numbers, better compression into
ranges can usually be achieved by carefully selecting the order of the
\bibitem entries or the order of initial citations when using BibTeX.
Having the entries pre-sorted will also save processing time, especially
for long lists of numbers.

Customization:
~~~~~~~~~~~~~~
Under LaTeX2e, there are six options for \usepackage{overcite}:

[verbose]   causes warnings for undefined citations to be repeated each time
             they are used.
 [ref]       uses the format `[Ref.~12, optional note]' when \cite[]{} appears.
 [nospace]   eliminates the spaces after commas in the number list.
 [space]     uses a full inter-word space with no penalty after the commas
 [nosort]    prevents sorting of the numbers (default is to sort, and a
 [sort]      option is provided for completeness).
 [nomove]    prevents moving the superscript cite after punctuation.
 [noadjust]  disables `smart' handling of space before a cite with note.

There are several commands that you may redefine to change the formatting
of citation lists:

command       function                   default
----------    -----------------------    ----------------------------
\citeform     reformats each number      nothing
\citepunct    printed between numbers    comma + penalty + thin space
\citeleft     left delimiter of list     [
\citeright    right delimeter of list    ]
\citemid      printed before note        comma + space
\citedash     used in a compressed range endash + penalty

The left/mid/right commands only affect the formatting of citations with
optional notes: \cite[xxx]{yyy}.  You may use \renewcommand to change any
of these.  Remember, these commands are extensions made by this package;
they are not regular LaTeX.  Some examples of changes:

1: \renewcommand\citeform[1]{\romannumeral 0#1}} % roman numerals ^{i,vi}
2: \renewcommand\citeform[1]{(#1)} % parenthesized numbers ^{(1)-(5)}
3: \renewcommand\citeform{\thechapter.}  % by chapter: ^{2.18-2.21}
4: \renewcommand\citepunct{,} % no space and no breaks at commas
5: \renewcommand\citemid{; }  % semicolon before optional note
6: \renewcommand\citeleft{(}  % parentheses around list with note
   \renewcommand\citeright{)} % parentheses around list with note

The appearance of the whole citation list is governed by \@cite, (for no
note) and \@citex (when a note is given).  For more extensive changes to the
formatting, redefine \@cite and/or \@citex.  For example, to get brackets
around the list of superscript numbers you can do:

\def\@cite#1{\mbox{$\m@th^{\hbox{\@ove@rcfont[#1]}}$}}
or
   \def\@cite#1{\textsuperscript{[#1]}}

after \makeatletter.

Related Note:  overcite.sty does not affect the numbering format of
the bibliography; the "[12]" style is still the default.  To get
superscripts in the bibliography (at any time) you can include

\renewcommand\@biblabel[1]{$^{#1}$}

in your personal style file, or include

\makeatletter \renewcommand\@biblabel[1]{$^{#1}$} \makeatother

directly in your document.  If this does not work, your LaTeX and/or
document style are very outdated.

\@extra@b@citeb is a hook for other style files to further specify
citations; for example, to number by chapter (see chapterbib.sty).

See also cite.sty for enhanced [5-9] type citations, and drftcite.sty
for draft mode citations.

% Version 1991: Ignore spaces after commas in the parameter list. Move most of
% \citen into \@cmpresscites for speed. Give the proper \spacefactor afterwards.
% Version 1992: make \citepunct hold the punctuation between numbers (for ease
% of changing).  Add \/ to allow hyphenation of previous word, and look better
% in italics.
% 1992a: Make it work with NFSS.  (Thank you C. Hamlin and Rainer Schoepf)
%
% Version 3.0 (1992):  Rewrite, including sorting.  Make entries like "4th"
% be treated properly as text.
% 3.1: Bug fixes (and Joerg-Martin Schwarz also convinced me to use \ifcat)
% 3.2: NFSS support was wrong--added \reset@font.  Suppress repetitions of
%      warnings.  Include \@extra@b@citeb hook.
% 3.3: Handle LaTeX2e options. Introduce various customization hooks.
% 3.4: Heuristics to avoid removing \hspace glue before on-line \cite.
%      Make \nocite ignore spaces in list, simplify. Aliases for \citen.
%      Compatability with amsmath (which defines \over).
% 3.5: Replace \reset@font with \selectfont so italics are preserved
%      Include \G@refundefinedtrue.  Fix cite-with-note bug (Lars Engebretsen).
% 3.6: Add nosort option.
% 3.7: Add nomove option; catcode preservation and global \@no@sparg for
%      french.sty; warnings in \nocite.
% 3.8: \citedash hook, fix token look-ahead (Heiko Selber), noadjust, babel.
