I didn't really see this mentioned (or maybe it was and I missed it?) but, as was more or less expected, the Borders.com portal will be shutting down soon.
Apparently, the library can still be browsed until October 14, and any orders placed will be processed by Barnes & Noble.
I'm not sure whether this means B&N has bought over the rights to the portal, or perhaps even the 'brand'? But even the Borders logo now carries beneath it the line, "Now Fulfilled by Barnes & Noble".
