Goodreads Librarians Group discussion

My first book will be released on June 21, and I would like to set up my author page in advance. The only instructions I see are to create an author's page from one's book being listed here.
I'd be grateful for some direction as to what I can do at this point.
Is it possible to add one's book and author page here, a month prior to release date?
Thank you!

If the book isn't yet on Goodreads you can request addition at 'adding new books and editions'
The first post there gives details of what is needed.
