DEC Fanfold Papertape Storage

What is the best way to store the clear blue plastic boxes full of DEC fanfold papertape? I'd been laying them flat, but that takes up quite a bit of space. I was wondering if it's safe to put them in a bookcase like a book, but I got to thinking this probably isn't a good idea for the papertape. Zane -- -- | Zane H.
