Voici une solution, solution qui consiste à redéfinir un nouvel environnement bibliographique, bibliographique copié du style par défaut (`numeric`). (`numeric`).
J'ai ici appelé un style `author-year` pour le support papier, et ce style , style, préfixé de la lettre `N` `N`, pour le support internet. Si les deux étaient des styles numériques préfixés différemment, ce serait plus direct.
Code-exemple:
Voici un code-exemple :
\documentclass[12pt,german, english,french]{report}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{fourier} \usepackage{babel}
\usepackage{csquotes}% recommended in output (biblatex)
\usepackage[backend=biber, style = authoryear, autolang=other, defernumbers]{biblatex}
\defbibenvironment{prefixnumeric}
{\list
{\printtext[labelnumberwidth]{%
\mkbibbrackets{%
\printfield{prefixnumber}%
\printfield{labelnumber}}}}
{\setlength{\labelwidth}{\labelnumberwidth}%
\setlength{\leftmargin}{\labelwidth}%
\setlength{\labelsep}{\biblabelsep}%
\addtolength{\leftmargin}{\labelsep}%
\setlength{\itemsep}{\bibitemsep}%
\setlength{\parsep}{\bibparsep}}%
\renewcommand*{\makelabel}[1]{\hss##1}}
{\endlist}
{\item}
