I am looking forward to visiting the new library at the Perelman; it was closed the last time I was there
From Lee Rosenbaum's article in the Wall Street Journal
"While the design gallery may be the popular favorite, the sunlit library in the Perelman is clearly the director's pick. In New York recently to tout the Perelman's opening and the main building's coming exhibitions, Ms. d'Harnoncourt exulted in the library's greatly enhanced ability to provide state-of-the-art public access to some 200,000 books and periodicals, which are housed in four times the space they'd had before. Not only a research haven, the library also includes display cases for rotating exhibitions of rare books and manuscripts. Its main reading room is adorned by four bronze figurative reliefs, representing the four elements, that had been designed by Paul Manship in 1914 for the AT&T building in New York but look as if they had always belonged between the large windows in their current abode. What's best about the library is that unlike some other museum research centers, Philadelphia's is not just for serious scholars and specialists but also welcomes casual knowledge-seekers, who can also browse through its offerings in an online catalogue."
