I use N8N and Airtable at work.
We used to use Make.com, and I actually like N8N more, it's much easier to debug and see what's happening as you build the workflow.
Airtable is irritating but also amazing.
The main advantage of both is that relatively non-technical people can do useful things. So while I'd often rather write code than use N8N, if I use N8N it means other people I work with can fix/improve it. Same with Airtable.
I'm not aware of anything purpose built that does this, but should be pretty easy to build something with Budibase or similar lowcode tool?
If you can be bothered putting in all the ISBNs into your database, it should even be pretty straight forward to implement a bar code scanner to lookup.
