Summary: We provide a reasonably sufficient condition for a countable family of operators to have a common hypercyclic subspace. We also extend a result of the third author and A. Montes, thereby obtaining a common hypercyclic subspace for certain countable families of compact perturbations of operators of norm no larger than one.

Keywords: Hypercyclic vectors, subspaces, and operators; universal families.
