In addition to the primary forms of citation, the citation commands \citeyear and \citename are provided as building blocks for more complex citations that authors may (from time to time) require. \citeyear behaves like the \cite command except that only the year portion of the citation label is used. For example,
\citeyear{btxdoc,latex}
produces btxdoc,latex.
The parenthesis around the year list may be omitted by modifying the command
name with a single asterisk (e.g. \citeyear*{btxdoc}).
\citename behaves like the
\citeasnoun command except that only the author name(s)
portion of the citation label is used.
For example,
\citename{btxdoc}
produces
btxdoc.The use of these commands does not trigger the use of abbreviated citations for subsequent \citeasnoun and img20.gif">cite references.
