The library presented preliminary plans to the LPC in 2002, in which it would build a new structure between 231 Madison Avenue and the original library's annex, to be designed by Italian architect Renzo Piano and Beyer Blinder Belle. The commission also sought to restore landmark status to 231 Madison Avenue, a move the library did not oppose. In 2003, the Pierpont Morgan Library's buildings were closed for construction and expansion. In the interim, it sponsored numerous traveling exhibitions around the country. The library reopened on April 29, 2006, as the Morgan Library & Museum. With the completion of the renovation, the private office and vault of J. P. Morgan was also opened to the public. A restoration of the main building's interior spaces was completed in 2010. The Morgan Library & Museum announced a four-year restoration of the main building's facade in February 2019, the first in the building's history. As part of the project, the landscape designer Todd Longstaffe-Gowan designed a garden surrounding the original library building. The LPC had initially expressed opposition to the construction of the garden, as there had not been a garden around the original Morgan Library. The agency approved the project after reviewing letters and other correspondences from J. P. Morgan, who had indicated that he had indeed wanted a garden around the library. In addition, Integrated Conservation Resources restored the main building. The project cost $13 million in total. The renovation was completed in 2022. Collection Manuscripts The most internationally significant part of the Morgan Library and Museum's collection is its relatively small but very select collection of illuminated manuscripts. Among the more famous manuscripts are the Morgan Bible, Morgan Beatus, Hours of Catherine of Cleves, Farnese Hours, Morgan Black Hours, and Codex Glazier. The Morgan holds a copy of the letter written by Andrea Corsali from India in 1516; this letter, one of five in existence, contains the first description of the Southern Cross. The manuscript collection also contains authors' original manuscripts, including some by Sir Walter Scott and Honoré de Balzac. Other objects include a Percy Bysshe Shelley notebook; writings from Émile Zola; originals of poems by Robert Burns; a unique Charles Dickens manuscript of A Christmas Carol with handwritten edits and markup from the author; and a journal by Henry David Thoreau. There are also writings from George Sand, William Makepeace Thackeray, Lord Byron, and Charlotte Brontë, as well
