# I'm having trouble using citation styles in BibLaTeX [duplicate]

I'm having some slight issues with citation styles. I want Harvard style citations, in the form of (Bethe, 1939). Here is my code:

\documentclass[11pt,a4paper]{article}
%\usepackage[top=1in, bottom=1in, left=1in, right=1in]{geometry}

\usepackage{graphicx}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{comment}
%\usepackage{natbib}
\usepackage{amsmath}
\usepackage[
backend=bibtex,
style=authoryear,
sorting=nty
]{biblatex}
\usepackage{float}
%\usepackage{cite}

%\bibliographystyle{alpha}
\begin{document}

Document here \cite{EPS}

\end{document}


Sorry for the clutter. Experimented a lot trying to get the bibliography to work. Here is my bibliography:

Using the citestyle definition in the preamble, this should display Harvard style, if the manual is to believed. Instead I get the title of the paper. Perhaps it has to do with the warnings given? Here:

• Try removing the \bibliography{biblio}. (but leave the \addbibresource...) Right now the .bib is being loaded twice, which will only cause problems. Plust \bibliography is deprecated in biblatex – PTNobel Dec 2 '15 at 2:26
