The `.' is the line number argument to getline(). It refers to the
current line.
:help getline()
The regex is looking for things like...
\nobibliography{SOMESTUFF}
and
\bibliography{SOMESTUFF}
...in the current line, and if found, the \zs and \ze ensure that only
SOMESTUFF is considered to be part of the match.

:help /\zs
:help /\ze
