Magen - Inquiring Professional Dog Trainer > Status Update

I am NOT actually reading (listening) to this book. I am listening to another by this author, Mind-Body Philosophy, ISBN: 78-1629973630. However, Goodreads has finally taken the step of HIDING books it has decided are not books, namely books which are given as lectures. Previously, they just changed the author to NOT A BOOK. So far, lectures like A Room of One's Own are still listed as books. Why the disparity?
