Unable to change author name in an ebook on iPad I have a Mac computer where I downloaded an ePub and then changed the author on the Mac in the list view of iBooks.


MacOS 10.12.6 Sierra
iOS 12.3.1 for the iPad


Then I dragged and dropped the ePub from iBooks to desktop. Then I airdropped the ePub to my iPad from my MacBook. The author name is showing accurate on my MacBook. I had the book transferred to my iPad and there it is showing the old name for the author. Deleting the book and re-downloading/re-editing didn’t help. 

Apple Books on iPad is remembering the old metadata and not updating the author name.

I have been trying to fix this problem for the whole night but nothing worked. I even deleted Apple Books from my iPad and reinstalled it but that too didn’t work. I need to organize my files and this issue is really frustrating. 

Can anyone help point out how I might make a change to the author data of an eBook I didn't author initially?
After hours of frustration, I finally found a solution to my problem by doing the following: 


Open Finder.
Click Go in the Finders menu and select Go to Folder.
Type ~/Library/Caches in the window currently displayed and click Go.
Locate the iBooks file and move it to trash. 
Airdrop the same ePub file to iPad.


Following these steps I was able to see the accurate and updated author name on my iPad.
