Accessibility: Books list is extremely hard to navigate

[Menelion]

Your AaxAudioconverter app is extremely accessible for screen reader users due to windowsForms native accessibility. Unfortunately, this is not the case with BookLibConnect.
For some reason, the book list in the library is almost impossible to navigate, instead of every list item (which should be a book title) "system.Drawing.Bitmap" is reported to screen readers.
I'm now myself into Windowsforms development, but I had only like half an hour to investigate so far. I'd be glad to submit a pull request but I need to familiarize myself with the code. If you guide me where to dig, it would be super kind of you.
