The transition from traditional, paper‐based publishing to electronic publishing presents many challenges for publishers and their constituents. Among the most significant are those that concern linking to articles that are available online and citing of articles that are now published online prior to (or even in lieu of) the final pagination and binding of paper issues. The solutions to these problems will have a great impact on the usability of the scholarly electronic corpus for the research community. In particular, the solutions must be easy to use, persistent, and scalable. Here we examine some pragmatic solutions (in use now) that satisfy these criteria and contrast them with other proposed solutions. The examples are drawn mainly from the experiences of the American Physical Society, but the lessons gleaned will have wide applicability.

Exact modelling of the earthquake location process in regions of dilatancy-anisotropy shows that failure to take account of the velocity anisotropy in the determination of local hypocentres can result in erroneous and misleading locations. In particular, the locations can indicate spurious migrations of foci from the true epicentral positions and the true depths of foci. These spurious locations may indicate planes of hypocentres deviating from the true fault plane. Observations of such phenomena have been noted several times in the literature. However, once the anisotropic model is known, a simple location program, incorporating the anisotropic velocity-variations, permits accurate location of local earthquakes using Pand first S-wave arrival times.
