Escape - A Puzzling Story

[triadtimes]

*sigh*

Yet another proof of my lack of intelligence. For I am stuck on the first puzzle like the justified retard that I am.

Spoiler below!

Can't figure out bookshelf combination, and I assume that we're not expected to just randomly drag books until we find it. I also assume the hint is in the poem but as I a fucking moron I can't make anything of it. Please assist a brainless shit like me in need.

I found the bookshelf puzzle impossible. though I found the right combination and the explanation from the hps file I seriously don't understand how anyone could have figured it out.

Spoiler below!

Have either of you found the note labeled "Combination"? Until you get that note there is no need to be pulling on the puzzle-books. Just wondering if you gave up before finding the note or after, because if it is before finding it then there's your problem. There are other things to do besides pulling books ya'know.
