Carrie-- This is a great list. Sorry for coming in late on this, I was away. But i want to chime in and add two of my own works. These account for objects but also the relationships people have with them, which ultimately is why they are even objects in the first place.
Shorter earlier article: Object Knowledge- http://reconstruction.eserver.org/Issues/091/wood&latham.shtml
Book, more recent: The Objects of Experience- http://www.lcoastpress.com/book.php?id=483
I hope these can be useful too.
