This masterplan by Jones & Jones is claimed to be the document that changed zoo design into what it is today. http://www.jonesandjones.com/work/pdf/WoodlandParkZoo_LRP.pdf
Does anyone know where the full 1976 masterplan might be available online, or if somebody's has it, could it be uploaded (I know it was availiable someweher a few years back, but can't find it anymore...)?
