I have an old paperback book that is starting to fall apart. I am aware of scotch book tape and will probably use that. But first I need to fix the spine. I am hoping someone can guide me on how to it and pages falling out. I’ve included photos.

As you can see the pages are starting to separate from the spine. There’s also a couple of pages that have completely come out.

Should I use archival glue to repair this? If so do I clamp it while drying? Any advice you can provide is appreciated.
