This quantity is the fourth c1assified bibliography of natural and organometallic crystal constructions ready through the Crystallographic info Centre, collage Chemical Laboratory, Cambridge, and released together with the overseas Union of Crystallography. the 1st 3 volumes coated the years 1935-1971. the current quantity offers references mostly to compounds whose struc­ tures have been mentioned within the literature in the course of 1971-1972. a couple of constructions released ahead of 1971 and passed over from the former volumes also are inc1uded. The association of entries within the 86 chemical c1asses is similar with the former volumes and the reader is noted the advent in Vol. 1 or Vol. 2 for an outline of the sensible use of the bibliography. There are 3 cumulative indexes within the current quantity: formulation, transition steel and writer indexes. All 3 conceal the interval 1935- 1972 and provides references to entries in Vols. 1-4.

Und er this association reprints ofpapers containing crystallographic info at the moment are despatched on to the Crystal­ lographic info Centre, Cambridge, even as they're despatched out to abstractors getting ready fabric for the Bulletin Signaletique.
