Structure Reports for 1964

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 intended 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 inter preted in terms of what was topically interesting. However, the amount of literature covering matters of structural interest has become so large that this policy can no longer be followed. From Volume 28 onwards, critical reports are only given on actual structure determinations. That is to say reports are only written on papers recording the determination of the positions of the atoms in structures. Nevertheless, Volumes 28 to 30 still do record much information on lattice parameters and space groups of the structures of alloys and compounds, although in the form of tables. From Volume 31 onwards, even this information is generally omitted and only full structure determinations are reported. One of the reasons for this omission is that such data are obtainable from the continuing volumes of Crystal Data.
