You can add a search box to your institution’s website that is limited to your content in the OAC, by copying an HTML snippet that's available through your OAC Dashboard -- and incorporating it into your site.

Here's an example snippet:

<form action="">
<input maxlength="80" size="30" name="query" type="text">
<input type="submit" value="go" style="background: #B24415; color: #fff; padding:2px;">
<input value="California Historical Society" name="institution" type="hidden">

You can see it in action on the California Historical Society's website.
