Abstract
We construct composite operators in two-dimensional bosonized QCD, whi ch obey a W(infinity) algebra, and discuss their relation to analogous objects recently obtained in the fermionic language. A complex algebr aic structure is unravelled, supporting the idea that the model is int egrable. For singlets we find a mass spectrum obeying the Regge behavi or.
