Need to add books to a series

[M.E.]

I need to add this book and my newest one (Snake in the Grass) to the Hero's Sword series. I follow the instructors, but every time I click Edit on the series page, I go back to my home page. How do I add the books to the series?

Only librarians can edit series. I have added the books to the series.

Thank you.
