Tags are a quick and concise way to pass along information in which your accounts might be interested in keeping track down the road. For example, you can tag a title “Local Author” for those authors who might live in the general area, or “Rep Favorite” for a title in your list that you particularly enjoyed. Co-op deals (5 for 50%, $75 newsletter credit, etc.), ARC availability, etc. all make for relevant tags. If you’re not sure what sort of tags your accounts find helpful, it pays to simply ask them.
You can find tags here:
To create a tag, simply type what you like, and hit Enter. If you’ve used a tag before, it will pop up so you don’t have to type the whole thing (and so you maintain consistency).
