What identifier is this?

Rellwood · 08-05-2021, 04:47 PM

Amazon lists this as a "Mobi7 ASIN" number, but It is on books that are from Amazon or have been sent to my Kindle. I am trying to import a list of data on books with these identifiers but there are no titles/authors this is just listed as an ASIN but the format is MOBI7.

I've seen them show up sometimes when I import MOBI files, but going through all my libraries trying to match the books by identifier only is difficult. If I knew what causes it maybe I can figure out better which books to look for.

Also, I have come across books with this as an ASIN and another similar string as the mobi-asin. So--- any suggestions? Is it possible that these are the books I sideloaded into my Kindles? They are all pretty old (the ones I have) so maybe these ar UUID?

asin:5341e3dc-0fdb-413b-b323-3c07f42dfc75

Yeah, its from books that have been transfered from my Kindle to Calibre - they are the books sideloaded onto my Kindle
