You'll then need to choose if you want a Set by Type which lets you list all of your Objects of a certain Type, or a Set by Relation which will list all Objects that contain the Relation of your choosing.
You can also create a Set by Type from the Object type toggle on a new document.
For example, project management may require Type: Project, for reading list — Book. From the Library, choose an Object Type, click "Create," and choose "Create a set."
This will then create a set of all the Objects with the Type: Books.
Now you have an organized selection of all your book objects entered into Anytype.
