Here the packages I use in my document:
\documentclass[envcountsame,envcountchap]{svmono}
\usepackage{subfiles}
\usepackage[utf8]{inputenc}
\usepackage{mathptmx}
\usepackage[bottom]{footmisc}
\usepackage{microtype}
\usepackage{stmaryrd}
\usepackage{amsmath}
\usepackage{courier}
\usepackage{mathrsfs}
\usepackage{amssymb}
\usepackage[all,cmtip]{xy}
\usepackage{faktor}
\usepackage{graphicx}
\usepackage{mathdots}
\usepackage[colorlinks={true},linkcolor={blue},citecolor={blue}]{hyperref}
\usepackage[frame,width=15truecm,height=23.5truecm,center]{crop}
Moreover with
\nocite{*}
\bibliographystyle{alpha}
\bibliography{mybiblio}
in the references I have the labels without square brackets; for example:
GW10. bla bla
instead of
[GW10] bla bla
I'd like to have the square brackets, can you help me?
Many thanks.
