I've posted about At the Zü before, but just recently I realized that the strip is being collected into books.
I consider this to be an underrated comic strip. It was only around for three years back in the late '90s so it was obscure even then. Still, it's nice that the strip is getting SOME availability.
Both books are being published via CreateSpace. I bought one and the printing's great. Planning to buy second one today.
See sample strips here. In the meantime you can buy the books here.
