I don't think the fact that you have to know them, or arrange for admission by appointment with them to view the artifacts is a problem that makes the term incorrect here. And as pointed out elsewhere in the thread, the artifact information is actually available on a website, which is more than I can say for a lot of museums. Many art collections are this way as are collections of antiquarian books, the latter which I guess could be called a library. Each collector has their own perspective on what is unique about their collection, and whether it is rare, and what the significance is vs. just a random selection of parts. As to the definition above, I do not know that that "exhibition" means that the public can just walk in. One is required to purchase a ticket to most museums now, and knowing the person with the collection is not a lot different of a restriction than having to buy a ticket.
