This post is inspired after I was doing a search on Google and it suddenly occured to me how many different types of Search Result Links (SRL) Google provide in their SERPs. So, I set in to research and find out as many search-links I could. Please care to add on to my findings as they may not be a complete lists. May be Matt Cutt would like to pile on few more SRLs here as reply. 
1) Search related to: Books, videos and other search terms links
These SRL are provided as add-ons to the keyword/key phrase you have typed to assist in a more close search result.
With Google purchasing YouTube in October 2006, it meant Google making YouTube’s videos more searchable and readily available in its search results specially in video search.
As you can see from the above image, Google pulls Books and videos links as search results in additional to offering relates search terms links.
Some times Google books links are also pulled as results as in below image to provide most accurate and comprehensive results as possible from its database.
Users who have Google desktop application installed, will see results pulled in from their local computer and shown as listings in the search result.
2) Images and Videos links:
Certain key phrases may have related results from Images or Videos database which Google show as additional links so that as a searcher I may look in for the desired results in images or in videos.
Also Google shows many more links from the same site, known as Sitelinks to assist searchers to directly navigate to a particular page and not having to visit website and search for links. You can read more about sitelinks from your Google webmaster tool under Links>Sitelinks section where you will see if Google has generated sitelinks for your website or not.
3) Local Time and Dialing code:
This useful feature of Google search will quickly tell you the local time of any city, country you want to know.
Google search can be a handy tool when you want to dial one of your friend aborad or client and do not have his/her Country or city code. Just type in country dial code and voila! you will get the code.
4) Google Map link:
with Google map getting popular and smarter, Google statrted showing location Maps of websites within the search results. So, a visitor wanting to know the location of the business, clicking on the “Show map” will take them to the location.
Isn’t this great where you not only see relevant websites to your queries but also the location map to find them. May be the next step would be to list Paid Ads (in a pop-up) of car rental businesses where you can hire a car to reach the business office.
When you narrow your search by adding city name, Google shows on top of the SERPs, list of various local business along with their location as well as contact details.
These local business listings includes Google AdWords Ad links as well (the rentangle area) mixed among natural listings.
5) More results from website:
Ofter you will see Google showing “More results from” link along with direct links to specific pages from within the website(s) prompting searchers to click and find further details. This happens when Google thinks searchers would be better served with additional details from the said website(s).
6) Time of Last Indexing:
Recently Google started showing while they test, the last time they indexed a particual website, within the search results, next to a website.
Though I did not see it again, I was lucky to have seen this unique feature, showing Google is forever experimenting on how to tightly integrate data and better organize within the SERPs.
I’ll be posting more interesting links in search results….. keep reading…
