How do I cite websites in vancouver style using bibtex

Question

I have seen some people suggest

note = {\url{http://example.com/}}
howpublished= {\url{http://example.com/}}

This works to a point but I need to explicitly say stuff like "[online]" and I cannot use note or howpublished more than once. The result is I cannot write complete references for my websites. This is the format I expected to use:

Author/Editor (use the corporate author if no individual author or editor is named)

Title (this should be in italics)

[Online]

Available from: URL [Date of access]

This is how it is meant to look:

European Space Agency. ESA: Missions, Earth Observation: ENVISAT. [Online]. Available from: http://envisat.esa.int/ [Accessed 3rd July 2008].

The relevent packages I am using are:

\usepackage[super,comma,sort&compress]{natbib}

\usepackage{url}

bibliography style:

\bibliographystyle{unsrt}

You don't mention which entry type you're employing, so I'll assume it's the @misc entry type. If this assumption is correct, the following structure might work for you:

@misc{esa,
   author  = "{European Space Agency}",
   title   = "\emph{{ESA: Missions, Earth Observation: ENVISAT}}",
   howpublished = "[Online]. Available from: \url{http://envisat.esa.int/}",
   note    = "[Accessed 3rd July 2008]"
}

Some details to note:

• the use of curly braces in the author field to denote the fact that it's a "corporate" author rather than a person with first name "European", middle name "Space", and surname "Agency",
• the use of the \emph{} command inside the title field, which is required because the unsrt bibliography style does not by default italicize the contents of the title field of entries of type @misc, and
• the use of curly braces in the title field to prevent BibTeX from rendering the words ESA and ENVISAT in (mostly) lowercase letters.
