If you have an iPhone or iPad, there is a free Access to Insight app (
http://itunes.apple.com/us/app/access-t ... 25338?mt=8), which is essentially the entire website wrapped in an application. So with this, you can have all the texts, with the links from the site, in your pocket. It's not the latest version of the site - the current version is 2010.08.23, not the 2009 date shown in the screenshots on the iTunes Store - but I'm sure that's good enough for most people.
You can add bookmarks to specific pages, but you can't search. You also can't change the font size, which isn't an issue on the iPad, where it's bigger, but for me, on an iPhone, the font is a bit small.
But it's free, and it's pretty much the entire site.
