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:

• {{Footer USA Swimming 1964 Summer Olympics|state=collapsed}} will show the template collapsed, i.e. hidden apart from its title bar.
• {{Footer USA Swimming 1964 Summer Olympics|state=expanded}} will show the template expanded, i.e. fully visible.

1964 USA Olympic Swimming Team roster from USA Swimming's website (www.usaswimming.org). Retrieved September 25, 2012. Please note that the following swimmer also appears on the official USA Swimming roster for the 1964 Summer Olympics: Kathleen Seidel. This swimmer was not a medalist or finalist in any event, and Sports-Reference.com and databaseOlympics.com do not list her as competing in the preliminary heats, so I have removed her from the navbox. I can only surmise that she was an alternate who did not compete at the Olympics. If anyone else can shed light on her status, please do.
