There are a lot of tutorials on how to load PDFs into iBooks, but none say how to backup or transfer them back to your computer. I understand there is a button to email them, but I probably have accumulated 100 or so useful pdfs on my iPhone. Is there any safe reliable (hopefully native) way to do this. I do not want to risk losing them. I'm using iCloud, does that back them up as well? Either way I would like to have an extra copy of them on my hard drive.
EDIT: I think if I click sync books, it will erase everything I have on my iPhone and only use what's on my computer the first time I do it right? I have never synced it before loading the books.
EDIT: I have never had them on my laptop, I got the into iBook by downloading them directly from safari into the app.
