How do I Create a Comment for a Book

It has occurred to me that I might use the Comments field for books in LT. I can't figure out how to do this for selected books in my library.

You click on edit, and write your comment in the comment field.

>2 MarthaJeanne: Thanks, I didn't go down far enough to see that field.

By the way, I assume that comment is just for me to see. Is that correct?

>3 JoeB1934: No. There is a separate "Private Comment" field that is just for you to see, but just plain "Comment" is public.
