Overview
Citation Standards
Chicago Manual of Style citation format for nonfiction books, with guidance on complete bibliographic information and annotation.
Why Chicago Style
Chicago is the standard for nonfiction book publishing. Using it from the research phase means:
- Citations are ready for the manuscript
- Fact-checker can verify sources
- Bibliography can be compiled directly
- Professional credibility from the start
Core Principle: Complete Information
Every citation must include enough information for someone to:
- Find the source
- Verify the claim
- Assess the source's credibility
When in doubt, include more information rather than less.
