Images: Google Images indexes more than a billion images in JPEG, GIF, and PNG
(Portable Network Graphics) formats. The Advanced Image Search lets users limit
searches by filetype, size of image, coloration, and site or domain.

Book Search: To use the book search, simply preface any search with the keyword
book or books. The first three results, if there are any matches, will come from
Google Book Search.
Groups: Google acquired Deja, the last remaining Usenet newsgroup search
engine, in 2001. Even before that, Google began its own Usenet archive in August
2000. The complete Usenet archive, more than a billion messages dating back to
1995, is searchable via Google Groups. In 2004 Google introduced "a new version of
Google Groups that includes a mailing list and discussion forum creation option to
rival Yahoo Groups' similar service. Also new is the ability for registered users to
keep track of their favorite topics using the star (~ ) feature. By clicking the star next
to a favorite topic, that topic is added to the user's "My starred topics" page. Postings
now appear in minutes in Google Groups rather than the hours it used to take.
Google Groups still offers both a simple and advanced interface to search the
newsgroup postings. Both interfaces are extremely easy to use. Google Groups not
only returns results (sorted by relevance or date), it also shows you the most
relevant groups for your topic. So a search on the term oceanography suggests I
might want to take a look at the related groups sci.geo.oceanography and
bioneLbiology.deepsea. Newsgroup searching in general and Google Groups are
discussed in greater detail in a later section.

Mobile SMS Search: This service is different from the SMS text messaging that has
been available at AOL, Yahoo, Live Search, etc., for some time. The new Google
SMS permits queries using mobile technology. Google's SMS service offers similar
services but with different shortcuts. It is open to all US subscribers using a "major"
US cell phone provider and also to most UK mobile subscribers. The US number is
46645 (GOOGL on most phones) and for the UK it is 64664 (6GOOG on most
phones). Google explains how to use the SMS search service and offers a number
of sample queries at its new SMS webpage.

Patent Search (beta): New for 2007, Google Patent Search now has its own
discrete page. Users could always search for US patents by number, but Google
decided to create a separate page for these searches. The new site offers many
advanced search options, including options to search by patent number, title,
inventor's name, assignee's name, US and international classifications, and issue or
filing date range. Even more valuable than the search options are the view choices.
