Formatting Clickable Indexes: EPUB Typesetting Rules
Indexes look messy on e-readers? Learn how to code clickable index hyperlinks and anchor references for EPUB.
Eleanor Vance

"Static index pages do not translate directly to reflowable ebooks. To make an index functional on Kindle or Apple Books, every listed term must hyperlink directly back to its source anchor inside the text."
Core Key Takeaways
- Building Clickable Index Hyperlinks
- Creating Back-to-Text Return Anchors
- Optimizing Column Spreads for Mobile Screens
1. Building Clickable Index Hyperlinks
Avoid using page numbers in ebook indexes. Link index terms directly to their corresponding paragraph HTML anchors inside the text.
- Use descriptive HTML anchor links for terms rather than page figures.
- Implement two-way linking so readers can jump back to the index.
- Validate hyperlink targets using EPUBCheck before publishing.
2. Creating Back-to-Text Return Anchors
Add return links at the end of referenced paragraphs so readers can easily jump back to the index page after reading terms.
3. Optimizing Column Spreads for Mobile Screens
Ebook index listings should display in clean, single-column layouts to prevent text overlap on compact smartphone viewports.
