Dear Eric,

We are limited in RDF in that we can only refer to URIs representing 
real things (or to text strings), not to the physical things 
themselves.  Thus, in my example,

    <http://***>  #  Publisher's URL for the book

represents the *book itself*, not a bibliographic reference to the book, 
while

    *; biro:isReferencedBy <http://*****)>**  # URL of your local web
    page containing bibliographic reference to the book *
    *; biro:isReferencedBy <http://www.amazon.co.uk/*****)>  # **URL of
    Amazon page containing **bibliographic **reference to the book*
    *; biro:isReferencedBy <http://www.lib.ox.ac.uk/*****)> .  # **URL
    of Oxford University's OPAC catalogue item about the book*

represent three different complementary bibliographic references or 
bibliographic records that all relate to this same book.  These may 
differ in form, e.g. the library catalogue entry will be more complete 
that the Amazon entry.  (I am always frustrated that I cannot find the 
Publisher and ISBN for a book from Amazon, except by reading inside the 
front cover!  Not sure what their API provides, though.)

Nothing complex to explain, is there?

David
