A site I recently acquired has a lot of good content that's been online for years. However, a lot of the pages are only accessible by clicking a form button. It seems Google wasn't following those links.

There are now a lot of sites using that (stolen) content. There are too many to chase down individually. If I change the linking so that Googlebot can access these few hundred content pages will Google see my content as duplicate content?

Wayback has archived some of this "hidden" content (about 10%)and I can therefore prove originality for some of the page. But trying certain text strings from these pages in Google suggests that Google hasn't indexed any of these "hidden" pages though they do seem to like the pages they can see.

The site is a very whitehat site, a PR6, thousands of inwards links, and highly respected in its industry.

How can I get Google to see that the content originated here? Do I even make this content accessible to Googlebot now? Will it mess up the rankings for all the other pages that are doing well in the SERPs?
