I want to sort my references by order of appearance rather than alphabetically, and I'm led to believe that I need to use the 'unsrt' style to do that. However, the 'unsrt' style doesn't support displaying URLs in the Bibliography (at least, not as far as I can see anyway).
How can I display URLs in my bibliography, whilst still sorting it by order of appearance?
I'm using BibDesk to create the .bib file, and a typical entry that I need to display with a URL looks like:
@webpage{iasi,
Author = {ESA},
Date-Added = {2011-04-11 09:12:00 +0100},
Date-Modified = {2011-04-11 10:09:33 +0100},
Keywords = {iasi, so2, satellite},
Lastchecked = {11th April 2011},
Title = {{M}et{O}p - {IASI}},
Url = {http://www.esa.int/esaME/iasi.html},
Bdsk-Url-1 = {http://www.esa.int/esaME/iasi.html}}
