We report progress in the computation and analysis of strong-coupling series
of two- and three-dimensional ${\rm O}(N)$ $\sigma$ models. We show that,
through a combination of long strong-coupling series and judicious choice of
observables, one can compute continuum quantities reliably and with a precision
at least comparable with the best available Monte Carlo data.
