I’m a little confused by what you mean but here’s my best answer
-table of contents: helps readers know where to look for certain chapters and such. (Organizes book) 
-heading: tells reader what a chapter is about
-caption: description of something 
-glossary: helps readers know certain vocabulary 
-bold faced words: attracts the readers eye
-label: helps to identify something or someone
-photograph: can help a reader better understand a text 
-diagram: informative and helps readers know more and understand better 
I hope this helps!!
