Ghosts haunt places like attics, old barns, and university libraries. They live in the minds of researchers seeking in frustration that missing document, pamphlet, or book mentioned in an earlier source. Even when the text of a document has survived in some form, researchers sometimes have gone to great lengths to find the original manuscript for the assurance that nothing more can be found there.
