[Air-L] Articles on the philosophy of value

I'm writing a paper on the value of enterprise portals in government, and want to include a brief section discussing the term "value". But I have a hard time finding good articles through my university's library resources, so I'm posting here to see if anyone can help me. If you happen to have written something on the value of government portals, that would of course be welcome as well. regards, Marius Johannessen master's student information systems University of Agder
