From Publishers Weekly This last volume of a trilogy represents the culmination of a monumental project the bringing into print of Lovecraft's stories in their definitive form, based on manuscripts and notes. This volume also contains the important study, ``Supernatural Horror in Literature,'' and repairs a long time need by providing it with an index. T. E. D. Klein, whose work has been influenced by Lovecraft, contributes a long introduction tracing the authors who themselves influenced Lovecraft, in particular Lord Dunsany. Among the stories are ``From Beyond'' and ``Herbert WestReanimator,'' both of which have recently been brought to the screen, ``Beyond the Wall of Sleep,'' ``The Lurking Fear'' and ``Under the Pyramid,'' this last ghost written for Harry Houdini. Joshi, whose long-time project this has been, has also provided a chronological listing of HPL's works.
