On the subject of uncontrollable laughter in libraries, when I was at University (circa-1980) I found in the periodicals library a magazine called - if I recall correctly the "Journal of Improbabilities", which was an American publication lampooning scientific papers.
Does anyone out there know if it still exists, and if so where I might find a copy?
Do you realise how impossible it is to remain silent in a library whilst trying to suppress a laugh? It makes ecverything even more hilarious!
