Additions and Corrections sidered more as lengthy abstracts than as a more detailed treatment of their subjects. Heterogeneous as well as homogeneous and enzymatic catalytic reactions are discussed, and electrochemical studies constitute more than a quarter of the book. While it is realized that the intention of the book is to concentrate on catalytic activation of carbon dioxide, it would have
been helpful to have had at least a survey of noncatalytic uses of carbon dioxide that could consume large quantities, such as C02 injection for tertiary recovery of oil. The greatest value of the book is that it is a reference tool for those who are not familiar with the subject and are interested in developing new technologies for C02removal.

Page 46. Paragraph 3 should read as follows: Several line8 of evidence suggest that the aliphatic dicarboxylic acids may most plausibly form from diarylalkanes,hydroaromatic compounds, or ethers as illustrated in eq 6-9. Although little is known about the types of ethers in these macerals, a substantial proportion of these ethers in coals and some macerals are heterocyclic or diaryl ethers.54@
