Is your suggestion for improvement related to a problem? Please describe.
Some ISBNs like 3-85869-197-6 and 3-549-05585-4 cannot be found on OpenLibrary or Ebook.de
Describe the solution you'd like
Add book-info.com as a third fallback source for checking ISBN Data.
Additional context
The HTML needs to be parsed. Seems pretty straightforward to parse the data with jsoup
