I had to ride down toward SoHo to see my doc yesterday (small issue--plus time for my regular STD tests), so I stopped in McNally Jackson Books and Barnes & Noble Union Square to autograph copies of Columbine (expanded edition, of course).
I did 8 copies at B&N, 3 at McNally Jackson Book. They both ship worldwide. Order info.
(I will try to get back to The Strand very soon.)
