The book content type is suited for creating structured, multi-page hypertexts such as site resource guides, manuals, and Frequently Asked Questions (FAQs). It permits a document to have chapters, sections, subsections, etc. A book may be collaborative, but doesn't have to be. Authors with suitable permissions can add or edit pages in a book, and can arrange and re-order pages within the existing document.
Books have additional navigation elements at the bottom of each page for moving through the text, the previous, up, and next links. The previous and next links will be printed as the titles of the previous and next nodes in the book. Additional navigation may be provided by enabling the book navigation block.
