There are no rules about this…it is an agency/transcriber decision. Many agencies I have worked with start new chapters on a new braille page…but not all of them. And I’ve never heard any agency make different decisions based on what type of book it is – the agency decision is the same no matter the material being transcribed.
You mention that in literary books you skip a line and start the new chapter – is that a book where you are not indicating print page numbers with a page change indicator? There ARE rules about blank lines and the page change indicator – see Appendix C in Braille Formats.
