Borders filed for bankruptcy this morning. Here's a live blog of reports and reactions from around the network.

5:00 p.m.

Wrapping up for now.

Two sets of business stories emerge from the day, one the direct impact on Borders stores, and the second the impact on the book publishing industry and the real estate industry.

The store closings are deep and broad, and it's very unusual to see accounts of metro areas that don't have any stores closed; Houston was one market that remained intact, and none of the stores in Maine closed. Otherwise, there's lots of people all around the net saying "they are closing my nearby Borders store".

Publishers and book distributors large and small have been affected by the closings. The ongoing speculation about how much creditors will be expected to recover has only started - one source put it at 25 cents on the dollar. The field of anime and manga publishing looks especially exposed, with a distributor (Diamond Comic) on the list owed almost $4 million.

The real estate industry is still digesting the news, as investors sort through the closing listings and match them up with property holdings. Agree Realty's press release stating that only 5 of their 14 Borders leases were affected was treated favorably by investors. Simon Property Group and General Growth are both expected to weigh in on the bankruptcy court's decision making.

There's lots of nostalgia, mixed with bitterness, on online forums like the Metafilter "Borders Bankrupt" post and the LiveJournal I work at Borders forum. Read Metafilter if you want nostalgia, and LiveJournal for bitterness.

The Wall Street Journal, in a story Borders Owes Long List of Publishers, quotes Jed Lyons of Borders creditor Rowman & Littlefield Publishing Group.

The Idea Logical Company "consults to book publishers and their trading partners about the changes engendered by digital transformation to every component of the value chain."

Metafilter: Borders Bankrupt. From OolooKitty: As much as I hate to see any bookstore close down, my local Borders really wasn't a bookstore anymore. A few years ago they actually took most of the books off the main floor and put them upstairs; the main floor was reserved for iPhone cases, greeting cards that played music, coffee mugs and cheap plastic gift items. I stopped going there; it was too depressing to walk into a bookstore and not see any books.

Among the creditors of Borders is Diamond Book Distributors, which is owed just over $3.9 million according to court filings. Diamond distributes graphic novels, manga, and comics to Borders, and had stopped shipments to Borders because of non-payment.
