The Cambridge Companion to Ovid seems to be a book worth reading, according to this Bryn Mawr Classical Review:
"The editor of this volume, Philip Hardie, is one of those responsible for the rise in Ovid's fortunes, and many of the contributors that he has recruited for this volume have done their parts as well. But the essays on the whole do not merely reprise earlier themes; and Hardie has also recruited some less obvious but highly suitable collaborators, with the result that the collection makes a striking impression and succeeds on two separate fronts. As a summary of where Ovidian scholarship has been, it is, with perhaps one or two caveats, very successful indeed; and as an effort to indicate fruitful directions for future work, the volume should have a stimulating effect."
