Hi,

how it is evaluated which book is on the device and in the library and which isn't?
I have the problem that some books are marked correctly and others aren't. I will make a detailed list to find out when books are marked correctly and when they aren't.
The strange thing is, when I delete them from the library and reinsert them, then nothing changes. They are still marked as not part of the library/device.

If I know the way the program evaluates this flag, I know why this happens.
