I am revising (still!) The End of Abundance.
In the book, I have used jargon (e.g., aquifer or increasing block rates) that has a particular meaning.
At the moment, I define the words when they first appear; if they appear often, I also have them in the glossary.
I am not sure how to highlight them. (I want readers to know which words are in the glossary or not.)
So, it seems that I can put the words in bold (as in a textbook), small caps or leave them plain (letting readers figure out if they are in the glossary). Note that I only intend to do this on the first occurrence of the word.
Any thoughts on this?
