Adding Another Tag to already tagged books

In our library we have many books tagged Bios and True Stories. I would like to add the addition Tag of Nonfiction to all these books. How can I do it without having to add the new tag onee-by-one?

At the top of the catalog page you should see a button with a lightning bolt. That's the Power Edit button. You can add/delete a number of things en masse that way, including tags.

>2 Watry: is a great way to do it, but you can also use tag view:

- Click "Tags" at the top of your catalog
- Find the tag you're looking for (e.g. "Bios & true stories") and hover over it, then click "edit"
- After the tag that's already in the box, type a comma and then the tag you want to add to all the books that have that tag
- Click "save tag"

Thank you, that worked!
