Thank you, Cindi! I appreciate your response... Knowing that it's not a cut-and-dried thing actually helps a lot. I was worried I was overlooking the obvious answer somewhere, but now that I know I'm not, I will evaluate the source material and use my best judgment to decide how to present it in my manuscript.
And I haven't participated in any of the webinars yet-- honestly I felt like most of them would be too advanced for where I was in learning the basics of braille transcription. But the one this Friday sounds very useful, so I will try to check it out! 🙂
