This site was built in 2011 on the Joomla platform, using a custom template and several custom modules in order to achieve the complex functionality that the client required. The intention was to build it so that the site could be scaled up to deliver thousands of documents, an intention that provided the biggest design challenge — bigger, even, than the custom Joomla modules.
This was the first (and one of the few) Joomla site I've worked on that required more than one template. Differences in one section of the site were causing the main template to become unmanageably complicated, so we built and deployed another for a few pages, despite the added maintenance load that causes.
I see that although the site remains in Joomla, the template has been revised since I worked on it last.
