This volume contains 30 refereed survey and research papers arising from the international conference in Dublin. Methods from model theory, category theory, infinite combinatorics, representation theory, classical algebra and geometry are applied to the study of abelian groups and modules. On the other hand, methods form abelian group theory are applied to general module theory and non-commutative groups.
