Sales have been on the slide for 11 years; even online sales have fallen. Over the past five years, the company has lost more than $1bn in value. Dozens of stores have closed. A shake-up in February resulted in the loss of 1,800 full-time jobs. If Barnes & Noble closes it will mark the death of the last major book chain in the US, leaving the field open to Amazon, which sells one out of every two books in the country, according to analysts. Closure is also likely to hurt publishers, who will become even more heavily reliant on Amazon. Big swaths of America will be left without a major bookstore.
