Re: errore bibliografia: help please

tra l’altro, provando a fare come mi dici tu, mi dice:
`samiam@penrose: ~/Desktop/prova_biblio > latex prova.tex
This is pdfTeX, Version 3.1415926-1.40.10 (TeX Live 2009/Debian)

! LaTeX Error: File `biblatex.sty' not found.

Type X to quit or to proceed,

Altre idee?
Inoltre, i siti come si mettono in biblio?

Grazie.
