WDYTYA is fond of showing their featured personalities donning white gloves to handle original materials. It's good television I suppose. But it isn't necessarily good archival practice. That's according to information from the University of Reading and the British Library referenced at http://reclamationandrepresentation.blogspot.ca/2013/09/archives-and-white-gloves-myth.html
Knowing this probably won't help when you encounter a worker bee employee at an archives paid and required to follow the institutions protocol rather than think.
