In this article we suggest a new approach to the systematic, computer-aided construction and to the classification of product-quotient surfaces, introducing a new invariant, the integer γ, which depends only on the singularities of the quotient model X=(C1×C2)/G. It turns out that γ is related to the codimension of the subspace of H1,1 generated by algebraic curves coming from the construction (i.e., the classes of the two fibers and the Hirzebruch-Jung strings arising from the minimal resolution of singularities of X).
