Review of the hardback: 'Acta Numerica is a fine achievement and I think we can expect to see it for many years to come. It sets itself laudable and important goals and has, to a large extent, achieved them. I believe that the volumes are of enormous benefit to our subject ... The editorial board should be applauded for having the vision and drive necessary to create and sustain such a high quality publication ... No mathematics library is complete without this annual publication, and I urge everyone working in numerical mathematics and scientific computing to read it.' Andrew Stuart, SIAM Review Review of the hardback: 'The quality of exposition and editing is extremely high.' Z. Angew, Math. Mech
