Hello, per this comment, we found that IABot put the original link again.
Example:
This bot edit. If u search about "https://books.google.com/books?id=vzZ71Eh5QvMC" you'll found 2 links before (1 original + 1 archived), but after IABot edit, it's being 3 (2 original + 1 archived).
I have investigated the cause, and it is because the archive URL snapshot is not identical to the original. If you notice that the original link points to a page number within the query, the archive URL does not. To the bot that means a different output is produced. This can be resolved by either removing the page from the original URL, or adding the page to the archive URL.
