Abstract :
This index covers all items papers, correspondence, reviews, etc. that appeared in this periodical during 1981, and items from prior years that were commented upon or corrected in 1981. The index is divided into an Author Index and a Subject Index, both arranged alphabetically. The Author Index contains the primary entry for each item; this entry is listed under the name of the first author and includes coauthor names, title, location of the item, and notice of corrections and comments if any. Cross-references are given from each coauthor name to the name of the corresponding first author. The location of the item is specified by the journal name (abbreviated), year, month, and inclusive pages. The Subject Index contains several entries for each item, each consisting of a subject heading, modifying phrase(s), first author´s name, and enough information to locate the item. For coauthors, title, comments and corrections if any, etc., it is necessary to refer to the primary entry in the Author Index. Subject cross-references are provided as required by the subject matter. Also provided whenever appropriate are listings under generic headings such as Bibliographies (for any paper with at least 50 references, as well as papers that are exclusively bibliographies), Book reviews, and Special issues.
