The 13 Best Museums in Philadelphia, From Art Galleries to Medical Museums | Condé Nast Traveler

"Occupying two brownstones in tony Rittenhouse Square , The Rosenbach is a house museum and rare book library with an awe-inspiring collection of British and American literature. The museum was once the private home of the Rosenbach brothers, rare book dealers who curated the libraries of some of America’s most influential families, including the Folgers and Huntingtons. The collection they amassed—now composed of some 400,000 items, ranging from rare books and manuscripts, to pieces of art, decorative objects, and furnishings—is widely considered one of the finest in the country. Between the two libraries on view, which are organized both regionally and chronologically, visitors can get a look at items including the second folio of William Shakespeare’s plays, Bram Stoker’s handwritten notes for Dracula, and the only surviving copy of Benjamin Franklin’s Poor Richard's Almanac." - Nancy DePalma
