The Various Types of Title Case #

As you may or not know, I'm the developer of Text Case, a text-transformation utility app for iOS and macOS. The app now supports tons of various pre-defined transformations and allows the creation of custom transformations, however, the app was originally based around one format, title case.

As the name suggests, title case refers to the capitalisation of text that is to be used as a title. But it's not something that has an objective set of rules. Instead, it's more of a rule that's based around personal style choices.

The most popular title case standards I've heard of are AP (Associated Press), APA (American Psychological Association), and CMOS (Chicago Manual of Style), but there are countless more.

And including the next planned release for Text Case, it will support a total of 9 different title case variations. Some are quite similar, however, as people like to stick to certain standards, I think it's important that there's a lot of options in the app. And since I've had a few questions in theist asking what the difference is, I thought I'd write a post to explain the implemented rules.

Please note, the implemented formats aren't carbon copies of the official standards, as some of the rules aren't exactly feasible to build into an automated tool. For example, a few standards have the rule to keep the second part of a Latin species name lowercase, and AMA seems to have a few rules based around greek letters.

But from the perspective of Text Case, here is how each of them is implemented:

American Medical Association (AMA)

Associated Press (AP)

American Psychological Association (AP)

Bluebook

Chicago Manual of Style (CMOS)

Guardian

Modern Language Association (MLA)

New York Times

Wikipedia


Hopefully this has answered some questions that people have regarding the different title case variants. But if you have any more, then I'd be very willing to hear them. And if you spot something that isn't right, then please let me know!
