# Add to Library
The **Add to Library** button becomes available when one or more items are checked using the checkboxes.
Upon clicking, opens the **Add to Library** dialog allowing to add the checked items to one the existing user’s libraries.
After selecting a library from the list and clicking the **Add Family Types to Library** button, the confirmation dialog will be displayed, where you could skip certain items or rename them if you like.
After clicking the **Confirm** button the items will be added to the chosen library.
You could see them in the [Library tab](https://docs.bimcat.org/user-manual/usage/library-browser/library).
Both the **loadable** family types (Doors, Windows, Columns, etc.) and the **system** family types (Walls, Ceilings, Floors, etc.) are added to the library as separate entities, without exporting their whole family.
