Place the wet book in a dry, cool place. Run a fan in the room to keep the air moving.
Place absorbent paper towels under the book and stand the book vertically with the covers slightly open. If the book cannot support itself, use bookends to keep it upright.
Position the absorbent paper towels between the front and back covers and the first and last pages of the textbook.
Change the absorbent paper towels that you have used for new pieces of absorbent paper towels as soon as they are full of water. Turn the book over, alternating standing it vertically right-side up or upside-down, each time you change the absorbent paper towels.
Lay the textbook flat and interweave absorbent paper towels between every 20 pages when the book partially dries from Steps 1 to 4. Change the absorbent paper towels when they fill with water, as you did previously.
Stand the book vertically and fan the pages open after repeating Step 5 until the book is only damp. Position the fan so that the air circulates into the textbook. Let the fan blow into the textbook until it is almost dry.
Lay the book flat. Place absorbent paper towels between the covers again.
Place a light weight on top of the textbook and leave it in place until the book is completely dry.
