General ⇒ natbib style

[cia09jh]

I am currently writing my thesis, and all of a sudden when I compiled my references went from being the author and date to just a number. I have tried playing with the natbib settings trying authorname etc but nothing will work has anybody any suggestions how I can fix this?

Hi cia09jh,

Welcome to the LaTeX community!

Without a minimal working example it's hard to say something definite but this sounds as if you changed the bibliography style or changed natbib's settings. Quoting the natbib manual section 3.1, Selecting numerical style:

By default, natbib is in author–year mode. This can be changed by

1. selecting a numerical bibliography style with predefined citation style, defined either in the package or in the local configuration file;
2. giving options numbers or super to the \usepackage command;
3. issuing \setcitestyle{numbers};
4. issuing \citestyle with the name of a predefined numerical bibliography style (like plain and use it with plainnat).
