Abstract
Low-x physics is reviewed, with particular emphasis on searches for deviati ons from Gribov-Lipatov-Altarelli-Parisi (GLAP) evolution of the parton den sities. Although there are several intriguing indications, both in HERA and in Tevatron data, as yet there is no unambiguous evidence for other than s tandard next-to-leading-order GLAP evolution. The framework of dipole model s and saturation of parton densities is examined and confronted with the da ta. Although such models give a good qualitative description of the data, s o do other, more conventional, explanations.
