was located by searching Chemical Abstracts and Bulletin Signa/etique. The table below summarizes the cut-off dates for the 25 direct-scan journals yielding most entries in Volume 14. The fully classified Chemical Diagram Index, first presented in Volume 13, is continued here. Volume 14 contains 3912 chemical structural diagrams, repre­ senting 98% of the compounds. The reasons for the omission of some diagrams are noted in the Introduction. This new index provides a rapid visual overview of compounds studied in 1981-82 and will, we hope, add greatly to the usefulness of the annual Bibliographies. The textual indexes in Volume 14 continue the system established in Volumes 9-13 and in the special volume Guide to the Literature 1935-76. The latter volume presents a set of cumulative indexes to the contents of Bibliographic Volumes 1-8.
