(Note: To create wishlists, first create an account on Bookshop.org.)

Creating A Wishlist (which can then become a registry):

You are able to add any book you find on the site to a wishlist on each individual item's product page.

You can either add to an existing wishlist or create a new wishlist from here.

Once a wishlist has been created, it can be viewed and edited from your user account:

From this view, you can create new wishlists, share public wishlists, and delete wishlists you no longer want.

Clicking on the wishlist name will bring up the contents of the wishlist and lets you add books to your cart, change quantities or remove a book. To make further changes click on "Edit This Wishlist" at the top right of the page. This will let you change the name, add a header text, rearrange the order of the list, and make a registry from your wishlist.

More about Registry Mode for wishlists can be found here.
