How can I find my own bookshelves?

When you are inside all the bookshelves, you can choose to filter on certain bookshelves.

In the app, you will see this option under the button "bookshelves". Here you can choose to filter on bookshelves that are shared with you, your own bookshelves, or bookshelves from Polylino.

On the web there is a button that says "filter", press it and select what you want to filter on. The button is below the three lines on the top left that open the side menu.
