This information is not consign in the metadata information. The only way I can verify it is or by the book cover or review the first pages. For that reason I need to compare libraries, because if the book cover are the same (rare but possible), I can find the difference reviewing the first pages.
I hope I have explained my problem better this time.

Again, sorry my grammar (I use Google Traductor for checking my grammar)
