With the release of Book Creator 4.1, we added a facility to retrieve deleted books from within the app.
Any deleted book will automatically be added to your Recently Deleted bookshelf and can be retrieved for 2 weeks (after which it will be permanently deleted and unrecoverable).
To retrieve the deleted book:
1. Tap on the dropdown in the centre of the toolbar to access your bookshelves (by default, it will say All Books).
2. Tap on your Recently Deleted bookshelf.
3. Tap the + icon to restore a book. It will be added back to your All Books bookshelf (and whichever bookshelf you are currently displaying).
If the app itself is deleted you can still retrieve your books for further editing provided they are on your iBooks bookshelf (i.e. you had previously exported your book to the iBooks app).
Retrieving an ePub file with your iTunes Library
1. Connect your iPad to you Mac/PC with a cable, and sync your iPad with your iTunes library.
2. To make sure the book you want is copied from the iPad to iTunes, check you've selected All Books in your iPad's Sync settings - see the screenshot below.
3. After the sync has completed, access your iTunes library and use the dropdown menu on the left to show all the Books in your library. If you have iBooks for Mac, you'll get a message here saying that your books have moved (see section below).
4. Right-click on the book you wish to retrieve and choose Show in Finder (Mac users) or Show in Windows Explorer (Windows users). This will display the ePub file on your computer’s hard disk (book files are usually located in your iTunes Media Library). You can then copy this file and import it back into Book Creator in the usual way using email, Dropbox, Google Drive etc.
Retrieving your books from iBooks for Mac
Since OSX Mavericks was released for Mac users, iBooks for Mac comes pre-installed and has replaced the Books section of the iTunes library. Repeat steps 1 and 2 above, but this time, open iBooks for Mac.
There is no longer a right-click to access the ePub file. The book files themselves are now hidden away in your Users > Library folder - here's where to find them. (Note - the ePub file will just be a string of numbers, not the name of the book - e.g. 591646134.epub).
But you can simply drag and drop the book you want onto your desktop, and it will copy the ePub file there for you. You can now send this file back to your iPad as per above.
