... What happened?
You had the good idea of bringing together all the dramatic works of this brilliant author. You are generally able to produce a solid, tight paperback book (see the FF poetry volumes, for instance). What on earth possessed you to produce precisely this important and useful in edition in such an appallingly low quality? It is downright laughable, you can hardly open the book without another page falling out of it. Please make amends, soon.
In the meantime, I recommend everybody out there who cares enough about Beckett to be interested in his complete plays to buy the box-set of the Grove Centenary edition in paperback. That is, I grant you, a more expensive item to purchase, but by no means unreasonably so, and it will get you four nice volumes with Beckett's novels, shorter prose, and plays, but more importantly, the books won't fall apart in your hands.
