In my one-day course, I show 3 rare books: a 1570 Euclid, a 1613 Galileo, and a 1704 Newton. Then my assistant carries each book, open to the title page, around the room so people can get a close look. We had a problem with people wanting to touch the pages of the wonderful books; and a few people would sulk if told they could not touch the pages. So now my assistant pointedly wears white cloth gloves while showing the books to signal that they should not be touched.

That is, unobtrusive instructions at point of use.
