This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.

To change this template's initial visibility, the |state= parameter may be used:

• ((David Macaulay|state=collapsed)) will show the template collapsed, i.e. hidden apart from its title bar.
• ((David Macaulay|state=expanded)) will show the template expanded, i.e. fully visible.

This Template is meant as a structure to let people navigate and add books by David Macaulay. a full list of books is on the National building Museum's site here.
