Well, it’s nearly a month old.

The new web indexing system is called Caffeine. Caffeine provides 50 percent fresher results for web searches than Google’s last index, and it’s the largest collection of web content that the search engine company has ever offered.

The new index seems to be a much more dynamic system compared to the old one, which had several layers.

“Caffeine takes up nearly 100 million gigabytes of storage in one database and adds new information at a rate of hundreds of thousands of gigabytes per day.”

Google has added a Bookmarks feature to My Search History, enabling you to quickly tag and comment any web page you’ve visited.

To bookmark a page, just visit it through Google Search, get to it in your Search History, and click the star icon.  Then click “edit” and type in any tags under the “Labels” heading. You can even add some notes in the box underneath that.  Once you’ve saved a bunch of sites, you can view them by clicking the Bookmarks heading in the left sidebar. You can show multiple tags at once by clicking all of their check boxes. You can also view your tag “homepage” on your Google Personalized homepage.

You can bookmark pages easily by drag this bookmarklet to the Links area of your browser: Google Bookmark.

Imagine Google in the future opens this up, letting users share their bookmarks and see bookmarking data in searches, we could see something very useful and popular (social bookmarking + Google search= ?).

Google unveiled a new service, Google Co-op (http://www.google.com/coop/). Users can create customized searches of specific Web sites and even generate advertising revenue, see the whole story here.

Gary Price pointed out on his Resource Shelf that Yahoo and Microsoft have recently released similar services. Also Rollyo is online for almost a year and Swicki from Eurekster all offer these types of tools.

New in Google Scholar: finding “Related Articles” Tuesday, 22 August 2006 3:13 pm

For every Google Scholar search result, you can now see a list of articles that closely related to it by clicking on the “Related Articles” link that appears underneath each result. The list of related articles is ranked primarily by how similar these articles are to the original result, but also takes into account the relevance of each paper.

This is extremely useful when authors/scholars in some fields (esp. those new fields) use different terminology for the same concept.

Finding sets of related papers and books is often a great way for novices to get acquainted with a topic. However, we’ve found that even experts can sometimes be surprised to discover related work in their area of expertise.
