Core Indexing Principles

The fundamental rules that separate good indexes from great ones

Think Like Your Reader

Index the concepts readers will actually look for. Consider their vocabulary, not just the author's technical terms.

Example: Index 'job interview' not just 'employment screening process'

Capture Concepts, Not Just Words

Index ideas and topics discussed, even when the exact terms aren't used. Focus on meaning over literal text.

Example: Index 'leadership qualities' when text discusses 'traits of effective managers'

Be Comprehensive Yet Selective

Include all significant topics but avoid trivial mentions. Aim for 5-7 index entries per page of content.

Example: Index substantial discussions, skip passing references

Use Consistent Terminology

Choose one term and stick with it throughout. Use cross-references to connect alternative terms.

Example: 'AI, see Artificial intelligence' then use 'Artificial intelligence' consistently

Technical Guidelines

Professional formatting and structure standards

Entry Structure

  • Use sentence case (capitalize only first word and proper nouns)
  • Invert personal names (Last name, First name)
  • Use specific rather than vague headings
  • Limit main entries to 6-7 subentries maximum

Page References

  • Use en-dashes for page ranges (45-52, not 45-2 or 45-52)
  • Show continuous discussion with ranges (23-28)
  • List individual pages for scattered mentions (12, 45, 78)
  • Use 'passim' sparingly for topics discussed throughout

Cross-References

  • Use 'see' for preferred terms and redirects
  • Use 'see also' for related but different topics
  • Keep cross-references concise and specific
  • Ensure all cross-referenced entries actually exist

Subentries

  • Arrange subentries alphabetically or chronologically
  • Use parallel grammatical structure
  • Make subentries specific and searchable
  • Avoid orphan subentries (single subentry under main heading)

Before & After Examples

See how applying best practices transforms index quality

Vague vs Specific Entries

❌ Before

Marketing, 45-89

✅ After

Marketing digital strategies, 45-52 customer segmentation, 53-61 ROI measurement, 78-89

Principle: Break down broad topics into specific, searchable subentries

Inconsistent vs Consistent Terms

❌ Before

AI, 23 Artificial Intelligence, 45 Machine Learning, 67

✅ After

Artificial intelligence, 23, 45 machine learning, 67 see also Automation

Principle: Use one consistent term with proper cross-references

Poor vs Good Cross-References

❌ Before

Leadership, see Management Management, see Leadership

✅ After

Leadership, 23-45, 67-78 see also Management styles Management styles, 89-112

Principle: Cross-references should enhance, not confuse navigation

Professional Quality Checklist

Step-by-step process for creating professional-grade indexes

1

Planning

  • Identify target audience and their likely search terms
  • Determine index scope (subjects only, names only, or combined)
  • Review similar books for indexing approaches
  • Set length target (typically 3-5% of book length)
2

Creation

  • Read entire book before beginning to index
  • Index concepts and themes, not just explicit terms
  • Maintain consistent terminology throughout
  • Create meaningful cross-references between related topics
3

Review

  • Check alphabetical order is correct
  • Verify all page references are accurate
  • Ensure cross-references lead to existing entries
  • Test index by looking up key concepts
4

Final Polish

  • Remove entries with only one page reference if trivial
  • Combine overly fragmented entries
  • Standardize formatting and punctuation
  • Proofread for typos and consistency

Common Mistakes to Avoid

Learn from typical indexing pitfalls

❌ Indexing Every Mention

Problem: Creating entries for trivial, passing references

Solution: Only index substantial discussions (2+ sentences or key context)

❌ Author-Centric Language

Problem: Using technical jargon readers won't search for

Solution: Include common synonyms and alternative terms readers might use

❌ Inconsistent Formatting

Problem: Mixed capitalization, punctuation, and reference styles

Solution: Establish style guidelines and follow them consistently

❌ Circular Cross-References

Problem: 'A, see B' and 'B, see A' creating loops

Solution: Choose one preferred term and cross-reference others to it
