Final answer:
The italicized words in the magazine clipping are used to highlight titles of longer works such as books and journals.
Step-by-step explanation:
The purpose of italicized words in various texts can be multifaceted; however, pertaining to the magazine clipping provided, the italicization serves to highlight titles of works. When it comes to academic writing or formal publications, the convention is to italicize the titles of longer works, like books and journals, while shorter works such as articles are typically enclosed in quotation marks. For instance, as indicated in the magazine clipping, book titles are in italics, and the omission of words for brevity while preserving meaning utilizes ellipses; quoting directly utilizes exact words within quotation marks or block quotes for longer excerpts.
