Ah, Karen, good point.  These wouldn't even map to the same Work, good eye.
So, while that *might* raise another flag, I'll let it slide, since that's
technically a teaching supplement or something.  But, good to know for
figuring out "related Works", perhaps.

So in the interest of the original question "Are these the same Expression",
let me add a few more examples:
Keep the original LC record - http://lccn.loc.gov/74194328

and add





http://mirlyn.lib.umich.edu/Record/002876189/Details#tabs (does the added
"Illustrator" entry change anything?)

http://mirlyn.lib.umich.edu/Record/004923703/Details#tabs (more 700 entries,
but with no relator subfields)

My question would be, given this seemingly not very edge case example, how
do we approach it?
