Have you ever heard about this book ? ( it’s said written by Gershom Scholem)

The name is called ‘The Kabbalah in Provence: the circle of RABAD and his son R. Isaac the Blind’ , aka ‘The Kabbalah in Provence: The circle of Rabbi Abraham b. David of Posquie`res and his son R. Isaac Sagi Nahor’ . As far as I know , it has a shorter name ‘The Kabbalah in Provence’ . This book is very hard to find . It seems that it has been wiped out from the Internet , and there’s nothing about it’s content. If you can provide me with a link to it , I would be very grateful to you.
