# How to change "reference" letter size

I use

 \bibliographystyle{abbrv}
{\small \bibliography{reference}}


for references. How can I change the size of the "Reference" letter?

• Welcome to TeX.SX! Please help us to help you and add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. You might also want to add to your question how you're including the pdfs etc. Why do you use the biblatex tag? Sep 28 '14 at 20:22
• Do you want to change the font size of the entries or the title or both? I assume it's not just one letter! Sep 28 '14 at 22:30

The bibliography uses either \chapter* or \section*, depending on the class you use. You can rewrite them as explained here. However, if you are using any package such as natbib or biblatex, you can explicitly define it. Say you are using article and want to have it displayed as a subsection:
\renewcommand{\bibsection}{\subsection*{\bibname}} %natbib
