"Books" option missing in ITunes (Windows 10)
I don't see a "Books" option in the dropdown menu (I see only "Music", "Movies", "TV Shows", "Podcasts", and "Audiobooks".)
I do have books and PDFs in my ITunes media library, and I can view those using the iBooks app on my iPhone 6.
I just got a new iPhone (8) and restored it from a backup of the iPhone 6, and found that only a handful of books were available in the iBooks app; the remaining had disappeared. Clearly the backup restoration was selective (music, podcasts, photos, and others were copied), and didn't include all the books (any ideas why?)
I would like to be able to sync all the books and documents from the old phone to the new one, but I don't know how to do that if ITunes doesn't provide a books option to let me manage such content.
Any help would be appreciated.
ITunes version: 12.7.1.14 (Windows)
New iPhone: 8: iOS 11.0.3
Old iPhone: 6: iOS 10.3.3
Thank you.
