Library

"The first thing naturally when one enters a scholar's study or library, is to look at his books.  One gets the notion very speedily of his tastes and the range of his pursuits by a glance round his book-shelves."

                                                                                ̶ The Poet at the Breakfast Table. VIII
                                                                                  Oliver Wendell Holmes (1809-1894)
