Starting with Volume 30, 1965, 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 pro hibitive. At that time automatic typing methods giving justified lines, etc. for photo-offset reproduction did not offer any saving over type setting, but hand typing of the manuscripts could give a considerable saving in production costs. In the belief that a publication that is too expensive to buy is of little value, the format has been changed sacrificing elegance to availability. The new format does not lead to increased length of the volumes since the information content of the typed and typeset pages is practically identical. How ever, the amount of work to be reported demands the eventual separation of Structure Reports into two volumes, A. Metals and Inorganic and B. Organic. It was convenient to introduce this change also at Volume 30, and with Volume 31 further to restrict the publication of crystal data, so that from 1966 onwards the reports deal almost entirely with complete structure determinations only. 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.

This Cumulative Index of Structure Reports is for the years 1961 to 1970 (Vols. 26 to 35). The Subject Index is arranged in strict alphabetical succession regardless of the construction of words, although in the listing of organic compounds certain prefIxes such as mono, 0-, m-, p-, D and L are disregarded. Nevertheless, some inconsistencies in the rendering of these prefIXes and others such as trans, cyclo and iso remain, and where a name is sought which contains these, it should be searched for both with and without regard for the prefIx. The Formula Index which lists Metals and Inorganic substances, is arranged in alphabetical order of chemical symbols. Organic compounds are listed in the Index of Carbon Compounds, which is indexed fIrst by C, then H with other elements following in alphabetical order of chemical symbols. A carbon compound not appearing in this Index should also be sought in the Formula Index. The scheme usually employed for the transliteration of Russian is given below. w. B.
