Supplementary title page in book done in Nemeth

I had a question about how a supplementary title page is treated in a math book to be transcribed in Nemeth code. Would it go by the literary rules just as the title page would? For example, if I have to braille the phrase “4th Edition” on this supplementary title page, can I use the ‘th’ contraction in 4th since literary rules allow it? I know the Nemeth rule would be to spell out ‘th’ in 4th, but I was assuming I could treat this page as literary like the title page. Thanks for your help.
