We review our current understanding of instanton effects in the large N_climit of QCD. We argue that the instanton liquid can have a smooth large N_climit which is in agreement with scaling relations derived from Feynmandiagrams. We also discuss certain limits of QCD, like the case of high baryondensity, in which the Witten-Veneziano relation can be derived from QCD and issaturated by instantons.Comment: 18 pages, to appear in the proceedings of the workshop on ``Large N  QCD'', ECT* Trento (Italy), 2004; v2 references adde
