Warm tones, luxurious textures, and classic lines that recall the past: These are the building blocks of a library with Old World style. A good desk should be one of the anchors in the room (some of the most exquisite are by Martha Angus). A stately open bookcase is another. And luxe accessories — woodgrain frames by Eccolo, trays in exotic materials like cobra and python by R & Y Augousti — are essential for finishing this timeless look.
