You can boil a pot of water and hold the pages over the steam carefully. Peel them apart gently - work slowly and they will peel apart.
Pages are grouped in small stacks of 32 pages. They are sewn together. Then all of the pages are sewn. Then they are glued into the cover.
The pages of a book are held together by the book's binding, which can be sewn, glued, or spiral bound to keep the pages in place. Additionally, a cover is added to protect the pages and give the book a finished appearance.
the process when sediments are glued together is called sedimentation
A Separate Reality has 272 pages.

To separate bricks that have been glued with Liquid Nails you will need Windshield Cut-Out wire. Begin pushing the wire between the bricks at one corner. Continue using the wire to separate the bricks.
Even if they are glued with ABS yellow glue, they will come apart. I have sometimes removed old glued in pipe from couplings by working a small screwdriver in between, then a bigger screw driver, then one side of long nose pliers and twisted. ( I do this only if the alternative is destroying a complicated section of pipe.)

The only way that really works is to immerse them in water for at least a day, then you should be able to pry them apart.
The process is called cementation.
