Oops, that's the same one I just ordered about 10 minutes ago.
Well, I checked the status of my ILL request just now and it was canceled on Sep. 25th with a note that the only listed copy was with a commercial vendor. I'm not quite sure what commercial vendors are doing in the ILL listing or WorldCat entries, but I have never studied the system.
I did not get a notification of the cancellation by email though which surprises me. However, the ILL notifications share many traits with SPAM email (e.g. Subject: Your Loan Request) so it may have been filtered. I just checked my trash but it only goes back to 10am on Sep. 25 and the cancellation was around 8:5x AM on Sep. 25th.
Missed it by that much, if there was an email. I would have liked to find the email so I could whitelist it.
