Good morning to all,

I have some problems when adding books to my library using my iPhone. In some cases, scanning an ISBN bar code with my iPhone returns a “Failed” search, but if I scan the same bar code with my iPad everything works just fine. Examples are the ISBNs 9788815295866, Titanic naufragio o cambio di rotta per l'ordine liberale; 9782080712943, Les liaisons dangereuses; and 9780241982495, We were eight years in power: an American tragedy.

I would appreciate if someone could tell me why I have this problem. For obvious reasons, I would rather use my iPhone instead of the iPad, as I want to create a library of books I would like to purchase, and I generally find them at various bookstores when I do not have the iPad with me.

To focus the troubleshooting, there are few issues I searched and excluded by myself:

1. All the books were properly listed in WorldCat, that I believe is Zotero’s first stop when looking for books;
2. Both the iPhone and the iPad have the same version of Zotero that is also the latest;
3. As highlighted by the examples, this problem does not occur only with “foreign” (to the US) books, as the last example, *We were eight years in power: an American tragedy*, is a US book; finally,
4. Network connectivity can be excluded, as both devices were connected to my home network when I was doing the data entry.

Thanks for your help

Roberto
