It's fascinating, how different visualizers can be. At least, I'm assuming you visualize these things. I know I am a very intense visualizer, and I adore maps, but I have just as much trouble with remembering names of states, countries, capitals, and precisely where they lie, as I do titles and authors, though I can tell you where the book sits on my shelves--or how it handled when I checked it out from the library fifty years ago. ("I don't remember which of Georgette Heyer's books it was, at least I think it was hers, but the cover was a vile pink, the girl on the cover wore a mid-sixties granny dress instead of a Regency-era gown, and the word Dratt was misprinted with two 't's in a conversation.") Talk about useless detail!
