Both myself and leonard Parker came up with a workaround (thanks leonard), namely if sum = ... + a n + b + c/n +... then Coefficient[Expand[n sum],n] gives b as required. Using the 3rd parameter in Coefficient does NOT work, as it includes the reciprocal powers of n as well as the constant b: Coefficient[a n + b + c/n, n, 0] gives b + c/n I don't know whether this was the intended behaviour or not...
