I am trying to use OSCOLA as referencing style in my legal paper. However, I am not able to get the desirable output. The minimal working example is here:
\documentclass[12pt,a4paper,twoside]{article}
\usepackage[T1]{fontenc}
\usepackage[english]{babel}
\usepackage{float}
\usepackage[style=oscola, ibidstyle=uc, ibidtracker=true, backend=biber, indexing=cite]{biblatex}
\usepackage[style=british]{csquotes}
\addbibresource{library}
\begin{document}
\section{Introduction}
This is an example to learn the use of Oscolla in latex. \cite{Keys2009}.
\end{document}
However, only citation key is appeared after the sentence. What I get looks like this.

However, I want an output like this.
I have also tried \footcite but it just places the citation key in the footnote instead of putting complete reference.


\addbibresourceshould have the full file name. Also, your\citecommand should here be\footciteor\autocite. – Paul Stanley Apr 10 '18 at 07:56
