To this Eighth Edition of the late Mr William Gardner‘s Chemical Synonyms and trade Names there have been added some 3,300 new entries, principally in the field of plastics, alloys and pharmaceuticals. A number of entries describing products known to the Editors to be no longer commercially available have been deleted, with the principal object of keeping the bulk of the book within reasonable bounds; but it has been possible to add nearly 400 names to the Index of Manufacturers to be found at the end of the book. The sum of these additions and deletions represents a net increase of about 10 per cent, in the scope of this Eighth Edition as compared with its predecessor published in 1971.

**** The standard reference in the field of chemicals for commerce, cited in BCL3 and Sheehy. This extensively revised edition includes some 40,000 trade names and chemicals, of which about 18,000 entries are completely new; 13,500 entries that now contain CAS or EINECS numbers; and nearly 3,000 manufacturers, more than twice the number in the ninth edition. Entries give definitions, classification, chemical formulas/descriptions, functions/applications, and manufacturers. Annotation copyright by Book News, Inc., Portland, OR
