One of the most significant items in the ever growing IKEA catalogue celebrates its 30th birthday. The BILLY bookshelves were introduced in 1979 and are still one of the big sellers. I myself don't have a BILLY. I love IKEA, as you might or might not know, but BILLY is not a practical way to store big books on art or photography. BILLY just isn't deep enough, so I still go with BONDE. Anyway, happy birthday BILLY and I will definately buy your Birthday-Book!
