RE: The correct formatting style of the word 'epub'

Yes, this. EPUB in all caps was registered as a trademark of IDPF (around 2010 or so, I believe). All the specs begins somewhere with “EPUB® 3”.

 

The informal spellings, like ePub, predate that.

The official way is in all caps. Of course, the extension is .epub, which leads to confusion, and the stylized logo does not help. However, let’s all use EPUB, whenever you refer to the Standard.

Interesting question Perer 😊 I do believe we came to the "decision" to use EPUB ones upon a time. But correct me people if I am wrong.

I don't know if there is an official way, but I have always used EPUB 
all caps in articles and presentations, and epub all lowercase in file 
names and variable names.

I guess if the E part had to be distinguished, the camelcase ePub is 
probably what I'd use.
