A bit further down the block at 456 Bergen St. is Unnameable Books aka Adam's Books. Here new and used books mingle. I saw a bunch of treasures tucked into the shelves and while the prices are a bit higher than I'd like the selection makes up for any miserly feelings. Along with books, Unnameable has poetry chapbooks, zines and a few minicomics. There was also a good size children's section.
On the way over from Atlantic station (the Bergen 2,3 stop was closed for construction) I spied a rather large Salvation Army.
All of this to say that I will be back.
