OK, for those of you who are looking for available books from Wilmann-Bell, I am sharing this link with you.
This is a Montreal based distributor (our local astronomy store). They still have a few books. I just ordered the Arp Atlas of Peculiar Galaxies.
They did not have Volume 7 of the Annals of the Deep Sky Series... If any of you know where I can find one, let me know!
