SUBJECT INDEXES. All subject indexes are prepared in the Editorial Reference Department of C&EN by technically trained indexers. Specific and general entries are carefully selected to make information retrieval speedy and rewarding. Individual articles are indexed in depth. Product announcements are indexed by subject and company. Books are listed by title and subject. NAME INDEXES. All individuals mentioned during each quarter are listed, with the single exception of authors of ACS National Meeting Papers. Names of these authors are regularly indexed in ABSTRACTS OF PAPERS and so are not duplicated in the C&EN Name Indexes. ANNUAL CUMULATIVE INDEX. This combined index will be available shortly after the fourth Quarterly, and will contain all entries from the four quarterlies to provide a single, cumulative index for the year.
