The present volume continues the aim of Structure Reports to present critical accounts of all crystallographic structure determip. ations. The increase in the number of crystal structure papers (now about 2000 per year in the Organic Section) has prompted a minor change in format, which increases the information density per page, hopefully without any loss of clarity. Details of the arrangement in the volumes, symbols used etc. are given in previous volumes (e. g. 41 B or 42A, pages vi-viii). J.

The general arrangement is: aliphatic or open-chain compounds; open chains with N, S; benzene derivatives; cyclic hydrocarbons; condensed ring systems; heterocyclic compounds; carbohydrates, amino-acids, natural products; molecular complexes; organometallic compounds - B, Si, P, As, Sb, groups lA, IIA, III, IV, VI; transition metal complexes - w-complexes, other ligands. Only com plete structure analyses are described; compounds for which only lattice para meters are determined, and those which have been described only in preliminary communications and for which details will appear at a later date, have not been reported.

This cumulative index of structure reports contains all the structures for the years 1913-1980 (Volumes 1 to 46B) and the authors for the latest 10-year period 1971-1980 (Volumes 37B-46B).

In the past the aim of Structure Reports has been to present critical reports on all work of crystallographic structural interest, whether it is derived directly from X-ray, electron, or neutron diffraction, or even indirectly from other experiments. The reports were in tended to be critical and not mere abstracts, except in some cases when a brief indication of the content of a paper of related interest was included in the form of an abstract. In selecting topics for reporting, the criterion 'of structural interest' was freely interpreted in terms of what was topically interesting. However, the amount of literature covering matters of structural interest became so large that this policy could no longer be followed, and from Volume 28 onwards, critical reports are given only on actual structure deter minations. Only in this way was it possible to keep yearly volumes to a fairly uniform and usable size. Starting with Volume 30, Structure Reports is produced in a new format by photo-offset printing from typed manuscript with unjustified lines. At the time when the decision for this change was taken, the cost of setting the manuscript in type was becoming so high as to render the cost of individual subscription prohibitive. At that time automatic typing methods giving justified lines, etc."

This Cumulative Index of Structure Reports contains all the structures for the years 1913-1980 (Volumes 1 to 46B) and the authors for the latest 10-year period, 1971- 1980 (Volumes 37B to 46B). The arrangement in the classified structure index is as outlined on pages VII-VIII. University of Guelph, G. FERGUSON Guelph, Ontario, Canada [VI] VII ARRANGEMENT Classified Organic Index (Page 1) Each entry gives the formula, name, and Strukturbericht and Structure Reports references. The entries are arranged in accordance with the classification scheme based on chemical structure of the Cambridge Crystallographic Data Centre; within each class the order is by formula. The formula index will help to locate a compound for which the classification is doubtful. The classification is: (0) Aliphatic hydrocarbons and derivatives 1 Aliphatic carboxylic acid derivatives 2 Aliphatic carboxylic acid salts (&JmOnium, IA, IIA . . tals) 3 Aliphatic lllllines 4 Aliphatic (N and S) COIIIJ>OWids 7 Nitriles (aliphatic and aroutic) 8 Urea compounds (aliphatic and aromatic) 9 Nitrogen-nitrogen c0111pounds (aliphatic and aromatic) 10 Nitrogen-oxygen compoWids (aliphatic and aroutic) 11 Sulphur and selenium COIIIpounds 12 Carbonium ions, carbanions, radicals 13 Benz.

The Reports are published annually and are divided into three main sections. A:(I) metals and (II) inorganic compounds; and B: organic compounds (including opgano-metallic compounds). The format of information in individual reports is: names, formulae, papers reported, unit cell and space group data, details of analysis, atomic positions, inter-atomic distances and angles, description and discussion of the structure (with diagrams), and additional references. The subject index is based on the names of the substances as given in the headings of the individual indexes are published as separate volumes. The Reports make the search through hundreds of journals unnecessary, as each volume gives the essence of one year's worldwide literature on crystal structure determinations. The series thus forms an essential bank of information.

Youth Justice in America, Second Edition engages students in an exciting, informed discussion of the U.S. juvenile justice system and fills a pressing need to make legal issues personally meaningful to young people. Written in a straightforward style, the book addresses tough, important issues that directly affect today's youth, including the rights of accused juveniles, search and seizure, self-incrimination and confession, right to appeal, and the death penalty for juveniles. Focusing on cases that relate to the Fourth, Fifth, Sixth, and Eighth Amendments to the U.S. Constitution, the subject matter comes alive through a wide variety of in-book learning aids.
