Glad to help.
You should get this one if you're buying any of the print-only books:
World Within Walls.
It's currently deep-discount bargain priced at only $15 and it's also part 2 of Keene's 4-book major overview series of Japanese lit (which started with Seeds in the Heart which is $48) and specifically says it comprehensively covers the haiku and other forms of the time that Basho was around.
