Crossing boundaries: computational science, e-Science and global e-Infrastructure

This is the second of two theme issues of Phil. Trans. R. Soc. A, which together contain selected papers from the UK e-Science All Hands Meeting 2008. The conference was held in Edinburgh between 8 and 11 September 2008 (http://www.allhands.org.uk/2008/). The papers that appear here have been through a rigorous peer review process, as described in the introduction to the first theme issue (Coveney & Atkinson 2009). Their quality serves to highlight the vibrant, interdisciplinary nature of the field and the impact it is having across an exceptionally wide range of endeavours, from the physical sciences all the way to the arts and humanities, as well as from the pure to the applied.
