This is exactly why we're building https://glideapps.com!
At my company we've built a slack bot that sits in front of a google sheet to manage transactions (eg. borrows) in our office library.[1]
I'd love to know whether this could be a Glide app, or whether we'd run into a technical limitation where we can't have users scan a book's ISBN and have that do a lookup in the sheet.

Few minor notes: - You've featured an app "Tournament of Books" but there are no links there. Both the title and the mock text conversation image can be links to that app - Interspersed fixed width font is jarring
