Used CD network?

The used book network is deep and well connected. Is there any such parallel in the CD market? I've asked many dealers, used and retail, to no avail. After exhausting the local used outlets, various online stores, Sterns NYC, and the producer I am still unable to locate a CD copy of Francis Bebey's Nandolo/With Love (OMCD 27), now out of print. Certainly, some store or person has it and would like to sell it. Any specific or general suggestions? Thanks!
