Portmerion Address Book (Downend BS16)

Portmerion Address Book with lovely floral illustrations.
This has not been used as an address book, but somone has written the names of 2 books by M C Beaton on the "B" section - see photo. I assume somone planned to keep a record of the books they read, by author, within this book, but changed their mind.
This could be covered with tippex or a sticky label.
I have not found any other writing in the book.
