Let’s be honest for a second: I have no idea what a “slug” is in relationship to AP style.
That being said, my lack of knowledge has not stopped me from thoroughly enjoying this style guide from 2002.
Here are my slugs, added to the book:
The Advance Slugs
Boldface Slugs, Slugging the Bulletin, and the Urgent Slug
The “Changes Dateline” Slug
The APNewsAlert Slug
Caution! Impending Slugs!
The Simple Slug and the Complicated Slug
The Urgent Slug, Part II
Double Urgent Slugs
PS: A slug, according to Wikipedia, is “a short name given to an article that is in production.” Translation: a draft. Additionally, “The keyword or slug (sometimes more than one word) clearly indicates the content of the story.” Translation: hashtag.
