The concordance group of classical knots C was introduced
over 50 years ago by Fox and Milnor. It is a much-studied and elusive
object which among other things has been a valuable testing ground for
various new topological (and smooth 4-dimensional) invariants. In
this talk I will address the problem of embedding C in a larger group
corresponding to the inclusion of knots in links.
