UPDATING QCD(2)

We review two-dimensional QCD. We start with the field theory aspects since 't Hooft's 1/N expansion, arriving at the non-Abelian bosonizati on formula, coset construction and gauge-fixing procedure. Then we con sider the string interpretation, phase structure and the collective co ordinate approach. Adjoint matter is coupled to the theory, and the La ndau-Ginzburg generalization is analysed. We end with considerations c oncerning higher algebras, integrability, constraint structure, and th e relation of high-energy scattering of hadrons with two-dimensional ( integrable) field theories.
