Italics are usually used for book titles. In fiction, italics often show what a person is thinking or some diversion from the main story.

Boldface type emphasizes some part of the story -- like section headings.

The use of boldface and/or italics in a piece of writing serves several purposes. Here are a few reasons why they might be used:

1. Emphasis: Boldface or italics can be employed to highlight important words or phrases, drawing the reader's attention to them. This can help to emphasize key ideas or specific details that the author wants to stand out.

2. Stylistic elements: Sometimes, writers use boldface or italics to add a stylistic flair to their writing. It can contribute to the overall tone or mood of the piece, giving it a unique style or voice.

3. Titles: In longer works, such as books or essays, it is common to use italics or boldface to denote the titles of works within the text. This helps to distinguish them from the rest of the content and follows the conventions of proper formatting.

4. Foreign words or phrases: When incorporating foreign words or phrases into a text, it is common to use italics to indicate that they are not in the reader's native language. This helps to differentiate them and make them stand out.

5. Quotes or citations: When including quotes or citations from other sources, writers may use boldface or italics to differentiate them from their own writing. This helps to clearly identify what is being quoted or referenced.

It's important to note that the specific use of boldface and/or italics can vary depending on the context, style guide, or personal preferences of the writer. To understand why they are used in a particular story, it is best to consider the specific instances where they appear and analyze how they contribute to the overall meaning or effect of the text.
