Happy #BookLoversDay! Did you know that a branch of @SILibraries is located at Cooper Hewitt? Our research library contains more than 80,000 volumes, including books, periodicals, catalogs, and trade literature dating from the fifteenth through the twentieth centuries. One of its special strengths is pop-up and moveable books—there are over 1,700 titles in the collection! “Paper engineer” David Carter designed this pop-up abstract that celebrates modern art and jazz, and also pays tribute to Mondrian and the Fauves.
