The back story to that is this: I'm thinking of compiling a book about local ghosts and so I visited the library, where there is said to be a spectre. The staff, one of whom I know quite well said that she and her colleague had worked there about four years and had experienced nothing. But she suggested I talk to another staff member who wasn't in this day (age disappeared for a while into the archives section but returned empty handed).
On my next trip to the library, I met said member of staff and I explained my interest he returned from the stores after 10 minutes with a thick folder marked "folklore".
The last attempt to compile a book was in 1986 and it produced a small pamphlet. I've contacted a lot of businesses etc in town asking about ghosts with an almost 100% failure rate! Even those places which have/had known spooks aren't talking!
