Ampersands in Titles

An ampersand is meaningful text, not merely decorative punctuation. Chicago normally limits ampersands in edited prose but preserves them in established terms, corporate names, verbatim quotations, and work titles that use the symbol.

Quick answer

If a title or protected name genuinely contains “&,” preserve it. Do not silently rewrite an ampersand to “and” merely to run a capitalization rule.

Important caveats

Automation boundary

Known names and verbatim titles take precedence over normalization.

Further guidance

Capitalization

The words on either side still follow the relevant title-case rules; the ampersand itself is passed through unchanged.

Preservation

Chicago allows an ampersand when mentioning a work title that contains one and preserves it in established company or brand names.

Punctuation Boundaries in Title Case

Colons, semicolons, and dashes can create capitalization boundaries in titles, while quotation marks and parentheses may introduce embedded structures that require additional analysis. This guide separates punctuation-boundary detection from word-class decisions so it can explain when a new segment begins and when it must leave the result unresolved.

Quotation Marks in Title Case

Quotation marks do not by themselves decide which words are capitalized. A converter must distinguish harmless outer quotation punctuation from an embedded title or quoted structure that may need its own capitalization and formatting rules.

Embedded Titles in Title Case

A title appearing inside another title has its own identity and may need quotation marks, italics, or language-specific treatment. Flattening the inner title into the outer title’s token stream can destroy both formatting and capitalization.
