In Roy's paper the functions are to sets of equivalent representations 
AND/OR (I don't remember how it was framed in the paper) URIs. The paper 
does not expand much on the latter, but I have taken him to be speaking 
of the URI used as 3xx redirection targets (though I have never tested 
that with him). Allowing the redirection to something else descriptive 
of said "solid, physical book on a shelf" does kind of make sense, 
though you may suggest tis to be post-hoc on my part.
