The author also wishes to thank Maris Rabollini of Rome, Italy for arranging a visit to the Vatican Library in 1993 to gather information on the use of oak galls for production of ink and to his wife, Patricia M. Ciesla, whose extensive collection of cookbooks provided much of the information on how to prepare the edible products derived from this diverse group of trees. Her equally extensive collection of literature on the fibre arts provided much of the information on natural dyes and the silkworm industry.
