International codificaiion efforss in the field of private international law have produced few direct results, but an increase in recent national codificaiions demonstrates that the latter issue from a rather common model as regards jurisdiciional and normative principles of unification. A comparison of national codificaiions makes it possible to extract the general pattern of this internaiionll model despite the differences and variants which remain. The multiplicity of codificaiion sources hence does not seem to be incompatible with the development of a genuine international harmonization of private internaiionll law.
