Abstract :
Following are two indexes: one for Volume 1 (Numbers 1 and 2, 1979) and one for Volume 2 (Numbers 1 through 4, 1980). Not listed in the indexes are brief mentions of companies, machines, and individuals in footnotes, references, acknowledgments, departments, and reviews. Major items in the two bibliographies (Randell, l/2, 101-207, and Van Sinderen, 2/2, 169-185) have been indexed and are denoted with an italic "b" after the page number (note that Randell??s bibliography has an extensive index on pages 192-207). Items mentioned on several contiguous pages are entered with an "ff" after the first page number. When an item is mentioned throughout an article, the inclusive page numbers are given. Figures and tables are denoted with "(illus.)" or "(table)" after the page number. We would be glad to receive suggestions for improvement of the indexes before they are used to create a cumulative index for future volumes. An index of each volume will appear in the first issue of the following year.
