60 years of IUCr journals
A. Authier
Synopsis: The birth and growth of the publications and journals of
the International Union of Crystallography from 1948 to 2008 are
described. Details are given of the pre-war history that led up to
their creation and development.

Topological relations between three-periodic nets. II. Binodal nets
V. A. Blatov and D. M. Proserpio
Synopsis: The TOPOS program package was used to generate all subnets
of 3- to 12-coordinated binodal nets taken from the Reticular
Chemistry Structure Resource database. 38 304 binodal nets with novel
topologies were revealed and stored in the TTD collection.

Crystal topologies - the achievable and inevitable symmetries
G. Thimm
Synopsis: On the basis of a link between a graph-theoretical
description of crystal structures and their symmetries, atom
positions are constrained. Examples show the presence of implicit and
forbidden symmetries.

Relationship between the atomic pair distribution function and
small-angle scattering: implications for modeling of nanoparticles
C. L. Farrow and S. J. L. Billinge
Synopsis: The exact relationship between the atomic pair distribution
function and small-angle-scattering equations is established and
discussed. This has implications for the structural modeling of
nanoparticles.
