LUB) then further on (!) to page 564 (for WES and WUB).
On the other hand, in cases where abbreviations are listed at the end of an article, when one no longer needs them, it is simply a waste of space (e.g., "IARC", Vol. 1, p. 310, and "ADI", Vol. 2, p. 578.
In the articles concerned with products one finds that the information given in the section "Economic Aspects" in each case varies greatly in the amount of detail and sometimes in quality. For example, under "Ammonia", "Adipic
Acid", and "Acrylonitrile" one finds a considerable amount of information about production capacities, consumption, and market growth, not only for the USA but also for Europe and Asia. In contrast, under "Anthraquinones" (Vol. 2, p. 81 1) the section "Economic Aspects" gives only one quantitative item, the price. Under "Alkyl Phenols" (Vol. 2, p. 128) the "Economic Aspects" amount to no more than a breakdown of the production costs, and under "Amino Resins and Plastics" (Vol. 2, p. 635) they consist essentially of a list of manufacturers occupying nearly half a page. Here the work could certainly have been improved by some systematization and unification of treatment, like that found in the corresponding sections of "Ullmann". However, despite the few shortcomings the new Kirk/Othmer, like its predecessors, is a work of reference in the top rank worldwide, and it is essential to every scientific and technical library as a complementary work to "Ullmann".
