That employees are scanning the barcodes or ISBNs on books — a unique serial number given to every published book — before scanning their content gives further credence to another theory put forth by booksellers: AI companies are trying to methodically scan every printed book in the world by working through the list of ISBNs. One bookseller told me they suspected this was the case because the very large orders they were getting never included very rare books that do not have ISBNs.
That's enlightening and ghastly. Great article, thank you.
