As you probably guessed, somebody figured out that if you can sew pages to one another to form a long scroll, why not sew them all together along one side? Yup, they did it and it worked! The pages are sewn along the left side. Not only that, they put a hard cover around the whole thing to protect the pages. This is called binding, and the style of book is called ‘codex.’
A codex book can be held in one hand and you can use a bookmark to remember a specific page.
Wow! Lots of photos show the process of binding a codex book—
You can even bind your own book— https://www.amazon.com/Bookbinding-VENCINK-Supplies-Binding-Large-Eye/dp/B075XK8RZ1
