Use roman type, capitalize, and use quote marks around the titles of lectures, book chapters, articles, papers, and other conference presentations, blog posts, most poetry, speeches, songs, and other brief musical creations, and TV or radio program episodes in running text. These guidelines also apply to business names and product labels. If you are writing about a particular class or category of things then it is appropriate to refer to them by class name: summer camp classes, college lecture courses, etc. If you cannot think of any specific thing that is a suitable topic for such a piece then we would advise against quoting class names as this makes your essay very vague. Quotes are used in journalism to credit the source of information or ideas. For example, when reporting the views of someone who has been quoted accurately but not by name, you should provide evidence of this interview with the quote attached. This shows that you have done your research and provides readers with a reference they can click on to find out more. Class names are useful when discussing topics that relate to several different things. For example, you could discuss the effects of inflation on savings accounts by referring to "dollar bills" or "coins". You would not want to use the word "money", because this is a much broader concept that relates to many different items including coins, paper money, bank accounts, and even commodities like oil or gold.
