How many books about the Beatles are written by women

I wonder: how many of the hundreds of books about the Beatles are written by female authors?
The only I know about is "Waiting for the "Beatles: An Apple Scruff's Story" by Carol Bedford.
Are there others?

there's one in the school lyberiy by john's half sister

2 by John's sister, Julia Baird: John Lennon, My Brother (out of print) and The Private John Lennon (can't remember what it's called in the UK.)
2 by Cynthia Lennon: A Twist of Lennon (out of print) and John.
1 by Pattie Boyd: Wonderful Tonight: George Harrison, Eric Clapton, and Me.
I KNOW there's more. These are the ones I could think of.

Women were fans during the Beatlemania years. They seemed to lose interest as time went on.
