General ⇒ bibliographystyle to have (very) short references

[Stephy]

hi everybody,

I have trouble to find the right command regarding my bibliographystyle,
I have recently changed my bibliography list as a 'bibliography-footnote" and it works perfectly
but now I'd like to change also the way it appears in my document, as a footnote it would be better if I coud make it a little bit shorter, in fact I'd like that only: first author, title journal, year and vol/page appearin the footnote-bibliography
but I'd like to keep the unsrt style
what is the right command I should use? I'm lost with all the possibilities I've found on the Internet
\bibliographystyle{unsrt, ???}

any suggestion is welcome!

thank's a lot
