Licensed? Yes. Stories? Yes. Intended to be part of the "Dr Who" universe? Yes. Officially released? Yup. These do seem to pass them all.

The stories retelling television serials should be treated in the same vein as novelisations: valid only to the point where they don't actively contradict the original. Only when they give any new information not in the other versions are they truly usable sources. Otherwise, it all seems to check out.
