I'm writing my graduation thesis but I can't add quotes in my work and I don't know why.
I made my bibliography with:
\begin{thebibliography}... and it works because when I compile my work I obtain the bibliography in my pdf file.

But when I try to quote some reference in my bibliography I can't obtain my quote

I'm sorry the language in the text is italian, but I hope you will understand anyway what is my mistake.
Please help me!
