They wouldn't because they knew we couldn't catalogue a collection. Cataloging is the main part of it, and cataloging is terribly expensive. Even cataloging regular books. The cost of getting a book on the shelf is twice to three times the cost of the book. Pretty horrifying thing.

In this case they also gave us endowment so we were able to continue the cataloging they had all ready started. But if you don't have an endowment you've got that enormous expense.

Anyway we're in the collecting business. We just got a couple of collections. We're getting the Toscanini papers, which we're announcing in a couple of weeks. You know, all in all we're quite a
