If you have a series of books, you don't have to send a separate message to record each book individually. Instead, you can record them all separately by just leaving a blank line between the topic and the list like this:

Books

The Fellowship of the Ring
The Two Towers
The Return of the King

That adds 3 entries to the Books topic rather than just 1. The extra newline after the topic name, Books, tells me to separate them.
