Book

The book module that up until Drupal 11 was part of Drupal core

A book is a set of nodes tied together in a hierarchical structure, with chapters, sections, and subsections. You can use books for manuals, site resource guides, Frequently Asked Questions (FAQ), novel, or curricula. Any content type can be added to a book, and a book can contain nodes of more than one content type.

Features

A version of this module was in Drupal core from Drupal 3.x until Drupal 10.x (around 22 years!)

You likely have used it since it's how the community documentation on drupal.org was organized for many years.

Users who have permission can create a book and write, modify, or rearrange the pages. Many users can work together on a book -- you can allow or disallow collaboration, to whatever extent you want.

Post-Installation

This module adds the "Book" content type. You will need to configure what types of nodes can be added to a book once it's created.

Replacing the Core Book Module

If you are upgrading from a Drupal 10.3+ site that used the core Book module,
Drupal will automatically detect and prefer this contributed version.

You do not need to uninstall or remove the deprecated core module.

Drupal's module discovery system prioritizes modules in the contrib directory
over those in core, looking for modules in `core/modules` last, after all the
other possible places that modules can live, ensuring a seamless transition.

For more details, see the official documentation:
[How to replace a deprecated core module with its contrib version](https://www.drupal.org/docs/core-modules-and-themes/deprecated-and-obsol...).

Recommended modules/libraries

• Book PDF - This module provides a means to print books and relies on a third party library for pdf generation.
• Book Access Code - Provide arbitrary access to books by exposing them to those that have a book code. This could be used in many ways.
• custom book block - A more configurable version of the navigation block
• book tree menu - Book Tree Menu enhances the default book navigation
• Booktree - Booktree module - take as input a series of Book nodes and create a tree-like structure using Book node relationships. Similar to booktree_menu.
• Sync book index to Drupal core menu
• Book Organizer

Community Documentation

A great place to add links to YouTube walkthroughs, external documentation, or a demo site (use DrupalPod!).
