Maps between local Picard groups

Abstract
We study the local Picard group of singularities. We study those elements in the local Picard group that become trivial either when pulled-back to the normalization or when restricted to a hyperplane section. In the second case we improve the similar results of SGA2. Version2: Many small changes, new Theorem 4 added.
