If you don't want to add those pages to the main navigatio of the site, then perhaps you could link them all together through a footer at the bottom of the page. Another option is to create a site map, link from the site map to those pages, link from the index to the site map, and link those pages to each other.
There are several alternatives, you just have to figure out what's best for your site and target audience.
