I have longed admired the look of books in a dining room. The library/dining room combination is certainly nothing new, but I think it's a great way to create warmth in a dining room. On the flip side, it gives the book lover an additional room in which to store books. This room multi-functionality is perfect for apartment dwellers and for those with small homes. If you own a large home with a formal dining room, why not take a small den, turn it into a library, and then use it for informal or small dinner parties?
