Q. Is there a Wish List in Libby?

Libby handles wish lists a little differently than OverDrive. Instead of one dedicated wish list, Libby uses "tags" to allow you tag books to create different lists or "tags". You can create a Wish List tag if you'd like and it would serve essentially the same function. 

To create a new tag, see Libby Help, Create a New Tag

To add an already created tag to a title, see Libby Help, Adding Tags to Titles

To add your OverDrive Wish List to Libby, see Libby Help, Adding your OverDrive Wish Lists to Libby
