I would suggest vacuum bagging. I've used it to fix soles to shoes and surfboard fins. You can buy the vacuum bag cheap on Amazon. I would first loosely fix the block of papers together. Add glue and tape to the binding edge then stick it in the bag, suck out the air and let atmospheric pressure fix it nicely.

Is this an alternative to the duct-tape method? Will the glue dry inside the bag?

An alternative to the clamps! I think the glue will dry without issues, though it can make a mess if there's too much.

PVA glue won't dry in a vacuum bag.

I see. I missed the _drying_ part. The moisture has to go away from the glue for it to dry. We can help here by placing a flat water absorbing material on the tape!

PVA glue will indeed dry in a vacuum bag. Most wood glues used for veneer pressing or lamination are indeed PVA glues and vacuum pressing is one of the best ways to get an even clamping pressure on complex or bent laminations.

PVA glue cures by eliminating moisture from the glue, and the low pressure of the vacuum will serve to accelerate the loss of moisture from the glue.

Gluing wood in a vacuum bag is kinda a special case - the moisture doesn't go into the vacuum pump - instead it absorbs into the dry wood.

Maybe the pages could absorb it?
