Current information on citrus production is available from the University of California's Division of Agriculture and Natural Resources at or from your local county Cooperative Extension Office.   [Vol. 1, Chap. 2, "The Commercial Citrus Regions of the World," was not included in this electronic edition because it is so severely out of date as to be potentially misleading.]   We have proofread these volumes many times and with several eyes, but because we have tried to make this available as soon as possible, there may still be errors.   If you find any, please let us know.
