Forget sleep (see below).  I have spent the last two hours researching off-the-shelf, self-assemble book-shelving.  Mostly office type stuff which is ugly.

But I have found one site with quick delivery and prices that don't scream rip-off (my bank manager might scream, but that's for later).

Now all I have to do is check my room measurements and the different sizes of my books, use the site's Design Wizard, curse and re-design, find a functioning Credit Card, and translate the assembly instructions into Polish...

Well, you didn't expect me to do it all on my own, did you?
