The New York Public Library exhibits ninety rare books:
Ninety from the Nineties is part of a tradition at The New York Public Library that began in 1968 with Sixty from the Sixties: An Exhibition of Distinctive Editions. Once every ten years since then the Library has mounted an exhibition of books acquired by the Rare Books Division during the preceding decade. These exhibitions featured books, pamphlets, broadsides, and printed ephemera from printers at work in the Americas, Great Britain, and Europe.
Here is the Times article on the exhibit.
