Use Biblatex and Biber instead of Bibtex,
\usepackage[backend=biber]{biblatex}
In combination with footcite replacement (see below),
\usepackage[style=verbose-trad1,dashed=false,backend=biber,autolang=other]{biblatex}
Define your bib files using addbibresource,
\addbibresource{latex}
The .bib file extention is optional on e.g. here latex.bib.
Note babel=other is depreceted. Use autloang= instead.
After that, eventually switch to footnodes instead of end of document references,
\let\cite=\footcite
Or simply print the bibliography at the end,
\printbibliography
add this below the biblatex package definition
\renewcommand*{\mkbibnamelast}{\textsc}
moar Biblatex enhancements
\DeclareNameAlias{sortname}{first-last}
\renewcommand{\newunitpunct}{\addcomma\space}
\renewcommand{\mkibid}{\emph}
eventually rename the bibloography section header
\addto\captionsfrenchb{\renewcommand\refname{EnquĂȘte et bibliographie}}
