Hi Jim.
You’re right but I’m sure you’d agree that a summary of, say, “War and Peace” and “The Gettysburg Address” might vary in length. I’m probably aiming more for the latter and my summary could use some word-smithing (among the many dozens of things I need to do to improve my site) in the meantime I wanted a way to just show people the end of the summary. Which you have now given me, thank you for that 
Matt
