Notes.
geometry package is assumed, the a4paper option is passed to it.cquotes package goes together with the babel package.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}
Notes.
.bib file extention is optional on e.g. here latex.bib.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
The last defined language becomes the default (here french),
\usepackage[english,ngerman,frenchb]{babel}
Add this below the biblatex package definition,
\renewcommand*{\mkbibnamelast}{\textsc}
Other Biblatex enhancements,
\DeclareNameAlias{sortname}{first-last}
\renewcommand{\newunitpunct}{\addcomma\space}
\renewcommand{\mkibid}{\emph}
Eventually rename the bibloography section header,
\addto\captionsfrenchb{\renewcommand\refname{Enquête et bibliographie}}
Built-in quoting feature: \quote{} and \quotation{}.
With \usepackage{csquotes} (that goes with babel) you can use \begin{displayquote} or \enquote{quote here}.
With \usepackage{dirtytalk} you can use \say{quote here}.
