The Cambridge Writers Collective held a contest every year starting in 1994 and they published an anthology containing all the winning poems, short stories and prose as well as selected other works. This continued for 10 years, culminating in the 10th Anniversary Anthology.
This is a rare opportunity to own the complete set. I only have one complete set, so act quickly if you are intersted. (I also have a few individual books that I will sell for $2.50)
All books are in reasonably good shape.
