I added some books for testing, now I’m done testing but I want to delete all of my test items and bibs and start fresh. How do I do it?

You can delete them all in MySQL.
** Please make sure you have made a backup of your data, just in case. We are not responsible for your lost data **

In your MySQL client, issue the following:

truncate biblio;

This will clean out biblio, biblioitems and items (by cascade), leaving you with a fresh biblio database for production use.

Additionally, until you clear the indexes, your deleted items will still be searchable in the database.
