need help choosing bookcases for heavy books

“i’m trying to figure out which bookcase would be best for lots of books (meaning something in which the shelves won’t be prone to sagging). the space for the bookshelf is approximately 76″ long by 18″ deep by 102″ high. i have a nice galant desk setup in beech veneer, and would like to match that finish if possible. i’d like the shelves to fill up the space as much as possible.” – kristine

kristine,
for heavy books, it would be better to choose shelving made from solid wood. the particleboard bookcases such as the billy or bonde system tend to sag under weight. as for solid wood bookcases, you do quite a few choices, though colour wise, you’re not so lucky. the norrebo (pic) in solid birch is a modular shelving system that lets you cover as much space as you want but the colour is not a great match. or you can also try the leksvik or ivar, which you could stain to match your desk.
