First off, the price was 39.11 so why was I billed 41.58.  
The instructions for assembly of this product are horrible.  I'm not sure an engineer would find them simple.  Finally got it together, without extra pieces.  This item certainly isn't designed for textbooks. It is rather flimsy.  A standard size book will not fit with all the shelves in place.  Granted, I should have measured a book, but it is a Bookcase.  With all the shelves filled, it leans forward.  Certainly not appropriate for a student needing a place to store textbooks.  Would probably be nice for just a few things on it, but I would not recommend this product.
