Yes.  A COinS object could/would allow users using LibX to be directed 
to my link resolver, to find an alternate licensed ebook copy of that 
book, to issue an ILL request for a print version, or to find a print 
version on the local libraries shelves.

It is important that the COinS object includes ISBN, LCCN and/or 
OCLCnum, if those identifiers are available for a given record. It is 
also useful it it contains a rfr_id identifying Open Library as the source.
