Hilco Merchant Resources already has a list of 200 Borders Stores that are on the chopping block, which was posted at the Wall Street Journal and is embedded below. Borders may end up adding 75 more stores to this list.
Update 1: There is another list now posted to the Borders Reorganization site. I've embedded that document below the first one.
Update 2: DJM Realty now has a page on its site with another version of the store closure list. DJM is handling the disposition. Their list includes information about the current rent being paid, extra fees, expiration dates and options. There's also an interactive map.
