Portentousness of Unconscious Power

I'd like to interrupt our scheduled program on behalf of those seeking more conventional annotations to Moby-Dick. Although I'm sure there are many fine sources of information, I've particularly enjoyed browsing Powering Moby-Dick. It's for the readers who wants to know, for example, where Corlears Hook is located or how far a league really is. These kinds of annotations can be a great help to the reader seeking to make sense of the many references in the novel. No, such notes are not necessary to the enjoyment of the text, in my opinion, but they are lovely in their way, a kind of color-coded poetry intended to help chart the Melvillean seas.
