Google's Skimpy Site Results

For all the subtle and experimental changes Google has been making to its results display lately, such as the jump to links and enhanced page links, and that Google even announced the changes (which does not always happen), I don't think I'd previously seen this particular approach to (what should I call them?) site links, or subsite links, or indented results from the same site. It seems related but not the same as the contextual show more results change from July.

You can see it in the screen shot below or try it yourself. For the past two days, I've seen the same results for this search on both IE and Firefox, and on at least three different computers. What's different from the usual indented display?

• Shorter snippets
• No URL
• No cache link (available for this URL on a different search)
  
• No "similar link (available for this URL on a different search)
• Links are tracked through Google (have a http://www.google.com/url?q prefix)
• And if you click on the "More results from endnote.com" you get no additional results

I found this less than helpful, since I wanted to judge the results by their URLs without having to mouse over the link to see it or clicking on it. The shorter snippets do not even show all my search words. And having a false "More results" link that gives none, is never helpful. This may be a short term experiment, or just triggered for some other, unusual reason. Time will tell.
