In order to save space, I would like to condense the bibliography, specifically, reduce the amount of vertical space between entries. Currently, it seems there is double-space between consecutive entries.

I use the "article" layout in LyX.

If you switch to natbib then there is a \bibsep parameter that you can adjust. – Andrew Swann Jan 18 '13 at 20:14
Thank you! I added this to the Latex Preamble: "\setlength{\bibsep}{0.0pt}" – Erel Segal-Halevi Jan 20 '13 at 12:12

As Andrew says, you can use natbib and then reset \bibsep:

\setlength{\bibsep}{0pt plus 0.3ex}

Without natbib, you can set \parskip and \itemsep to zero (they are responsible for the vertical space). It is advised to add some glue-stretch that can be used if necessary (this is what plus 0.3ex is for).



  \setlength{\itemsep}{0pt plus 0.3ex}



\bibitem{a} \lipsum[1]

\bibitem{b} \lipsum[4]
