(This must be a duplicate, but I cant find this asked anywhere so...)
I am trying to make a bibliography in a LaTeX document. Currently I am successfully using a back-end of Bibtex in Biblatex. In the header I have
\usepackage[backend=bibtex,style=numeric,citestyle=numeric]{biblatex}
\addbibresource{Bibliography.bib}
in my document I cite using
\cite{bk:soulsby:1997:dynamics_sands} \cite{ppr:pyle:1989:tephra_fall}
and at the end I output
\printbibliography
The bib file is
@book{bk:soulsby:1997:dynamics_sands,
author ="Richard Soulsby",
title ="Dynamics of Marine Sands",
year ="1997"
}
@article{ppr:pyle:1989:tephra_fall,
author ="David M Pyle",
title ="The thickness, volume and grainsize of tephra fall deposits",
journal ="Bulletin of Volcanology",
year ="1989"
}
I would like to use the biber backend, but changing the line in the preamble to
\usepackage[backend=biber,style=numeric,citestyle=numeric]{biblatex}
results in all citations displaying [tag_name]. How do I fix this?
