What are tags?
Tags are a flexible way to organize books in Libby. You can tag books from all of your libraries and create as many tags as you'd like.
Your tagged books appear under Shelf > Tags.
You can borrow or place holds directly from your tags lists, and you can export, filter, rename, and delete lists of tags.
Tags are specific to each device and don't sync between devices right now, but we're planning to add tag syncing to Libby in the future.
