This text, long out of print, is always highly sought-after. We have located and acquired a small number of copies of this important reference title and so are now pleased to be able to make it available to our customers. Please note that the copies available are second-hand items, and as such may be missing the original dustcover, may show some markings, may have been recovered, or may have markings indicating that they were formerly the property of a library. However, they are all in good legible condition with no pages missing or other serious damage.
