Here's why:
* Modern Style: Underlining is an older style of formatting. Today, we typically use italics for book titles, and that includes booklets.
* Consistency: Italicizing titles across different types of publications (books, articles, booklets) helps maintain a consistent style.
* Clarity: Underlining can sometimes be confused with a link, especially in digital documents.
Here's how to properly format a booklet title:
* Italicize: *The Complete Guide to Birdwatching*
* Quotation Marks: If the booklet is part of a larger work, use quotation marks. For example: *The History of the American West* ("The Pony Express")
Exceptions:
* Specific Style Guides: Some style guides might have specific rules regarding booklet titles. Always refer to the guidelines for the specific publication or organization.
