From the Home screen you can click on My Cookbooks. You can add and view cookbooks from the My Cookbooks screen. From the menu (three dots) in the upper right you can select to see the cookbook titles in Picture View so you see the covers you have added.
If you view the Titles View you can click on the sort arrows in the columns above the cookbook titles to sort by alphabet or by date edited or by type (group vs. regular).
When you create a cookbook you can choose to create a group cookbook. This allows you to collaborate with others.
Basically you can create two types of group cookbooks: (1) read-only--where you invite others to view recipes in your cookbook and (2) Others Can Contribute--where others can view recipes you've added as well as add their own. The person who contributes the recipe is the only one who can edit that recipe. Others in the group cannot edit each other's recipes. However, the group cookbook owner can edit anything in their group cookbook, even recipes added by others that have been invited to the group cookbook.
When you invite someone to a group cookbook they will receive a link to your group cookbook in email. They need to use that link. If they don't have an account at MasterCook.com, they will need to create one first. They can have a free MasterCook.com account and view your group cookbook. The recipes that others add do not count towards their recipe limit either.
Once you create a cookbook (regular vs. group) you cannot change it to another type. You can adjust the setting at any time to make it read-only or not for your group members.
You can view your recipes by going to the My Cookbook screen and opening a cookbook or go to the My Recipes screen.
