Hello Everybody,

first off Happy thanksgiving day

I need help or advise.

i have a third generation iPad stuck on iOS 9.3.5
i have been having issues with it lately! It has been slowly saying it's goodbye for the last year but now it's giving big bat signals!

i have almost 1800 books in there some I purchased from iBooks/iTunes Store (722 books) some from my own library and some books I've gotten here .
When I connect the iPad to my iTunes it only show me that I have 801 books.
i downloaded a trial version of apowersoft phone management also there I only see about 800 books

How do I not loose all the books? I had even made collections and organized some books into series/ authors
I have an iCloud account so it does back up but I am not sure it it will backup the non iBooks/tunes purchased books.
any help or advise would be appreciated

thanks in in advance to anybody who answers.

Amy
