The aim of this paper is to classify numerically effective holomorphic vector bundles£ on complex projective spaces and smooth quadrics, whose first Chern classes Cl (£)= 0, 1 or 2, the latter case on the projective space IPn only. The complete lists are given in theorems 1 and 2 below. We call£ to be numerically effective if the relative very ample sheaf on IP (£) is numerically effective.The need for such study arose from our work on classifying ample (n-I)-bundles£ on smooth n-dimensional manifolds X such that Cl (£)= Cl (X), see forthcoming paper [9]. In particular, theorems 1 and 2 from the present paper. together with the comparison lemma from [9] yield the following.
