Query: A good Lovecraft book, but definitely not a great one

OK, let's be clear on what this book is not. It is NOT an attempt to create H.P. Lovecraft's frightening, though fictitious, book, the Necronomicon. What this really is, is a sort of dictionary of the Lovecraftian mythos, containing entries on various places and creatures.As for me, I found the first chapters to be quite excellent, especially those focusing on the seven Great Old Ones. After that, the chapters or entries become increasingly less creepy, and consequently less entertaining. It's a good Lovecraft book, but definitely not a great one.
