Email a Random Open Library Book

Choose a random book from an Open Library subject and email a recommendation.

Setup

In Open Flow connect SendGrid and set the verified sender and recipient in both email nodes. Set the subject slug in Choose the subject. In n8n connect SMTP to both email nodes, set the addresses, and set the subject in Set Subject. Activate one format.

Behavior

Run manually or every Friday at 11:00 UTC. The workflow counts works in the subject, selects one at random and emails its title, linked authors and available description. If no works are found, it emails a no-book notice. A missing description is shown as unavailable. Open Flow runs on the minute boundary; the n8n Cron V1 trigger uses a fixed second within minute 00. An unknown email outcome may have succeeded; check sent mail before retrying.

Changes to the source

Repair the random offset and malformed work URL, use HTTPS, and handle descriptions returned as strings or objects. Escape book data in HTML and use UTC in both formats.
