Need to add two books to two individual series

[Sadie]

Apologies if I mess this up, it's my first post of this kind.

I have the fifth of my books Demon Bonded Episode Five: Beneath the Darkness to go into the Demon Bonded Series and the third Bullying Teacher 3 to go into the Bullying Teacher Series.

I tried to do this manually on my own by following some tips I found about altering series from books currently in the series, but I couldn't find the edit button when it came to the series. Sorry if I'm missing something but help would be greatly appreciated.

Thanks in advance ^^

Only librarians can add book to a series, authors can't.

Added both books to their series.
