It’s confirmed; Duncan first reported it yesterday and it appears in today’s paper (E-edition online only; no link). They’ve been downtown on Minnesota Avenue for 35 years (though not at the exact same location). 35 years! I don’t even know what to say.
(And before anybody points an accusative finger as to supposed lack of community support, yes, I have bought books from them.)
On the bright side, they plan to continue to exist online (and take phone orders starting June 1). I hope that works out for them.
