A Quick Tour of Google
Google is far more than a search siteit has grown to be a
sizable collection of services and tools, and the collection is getting larger
all the time. No longer is Google a single search site; instead, it's a
conglomeration of multiple sites. And no longer can you even call it Web-based
because Google now includes software that you download and run on your PC.
This book often refers to tools and services. Although there is
a lot of gray area in the definitions of these two terms, generally a service is
a website run by Google. So, for example, the bargain-finding site Froogle
(www.froogle.com) is a service because it's a Google-run
website; you have to visit it on the Web to use it. Google's image-management software Picasa
(www.picasa.com), on the other hand, is software that you
download to your PC, and so it considered a tool.
So where are the gray areas? Google Earth is an example of
something you could consider both a tool and a service: You have to download it
and run it on your PC, but you also have to be connected to the Internet to use
it because it gets all its information from Google online. The same holds true for the Google Toolbar, which you download and use on your PC, but
also use to search Google.
This book covers all of the major tools and servicesor at least
those that were available during the writing of the book. Google introduces new
tools and services all the timeand changes or updates its existing onesso what
you see when you head to Google might be slightly different from what you read
in this book.
Because of that, before reading the rest of the book, it's a
good idea to take a quick tour of Google so you can find the newest tools and
services on your own.
Note
When you use Google's tools and services, you'll notice that
many of them are labeled as being Beta.
Traditionally, beta software is software that is still in
the testing phase, is still being worked on, might have bugs in it, and might
have features that will change. But Google is extremely
liberal in applying the term beta. In fact, for Google, the term is essentially
meaningless. A Google tool or service might be labeled beta for a year or more,
even if it has no bugs and doesn't change.
The nearby figure shows Google's familiar main page. To do a search, type your
search terms in the search box. But look beyond the familiar search box. Across
the top-right side of the page is a series of links. The links show that I've
already signed into Google because the links include Personalized Home, Search History,My
Account, and Sign Out. If I hadn't been logged in, only two links would be there:
Sign In and Personalized Home. (And when I clicked the Personalized Home link, I'd
first have to sign in before I could get to my Personalized Home page.)
The links do exactly what they say. Click the Personalized Home link to go to a personalized,
customizable home page that includes news stories, information feeds, stock and
weather information, and more. (For details on how to set it up, start with About
Google Personalized Home.) Click the Search
History link and you come to a page that includes all the searches you've
done while you've been logged into your Google account. (See Add Bookmarks and Your
Search History to Google Personalized Home.) The My Account link enables you to change your Google
account settings, which were covered earlier in this chapter. And the Sign Out link, obviously, allows you to sign out of
your Google account.
Note
Why should you ever bother to sign out of your Google account? Shouldn't you simply stay
logged in forever? Not necessarily. The
main reason to log out is to protect your privacy. While you're logged in,
anyone using your computer can make full use of your account. This means they
can read all your email in Gmail, send mail
from Gmail, see your search history, and so
on.
Now look at the links just above the search box. These links
lead to several of Google's main services and tools. These links might change
over time, but at the time this book was written, they linked to Google Image Search (Images); Google
Groups (Groups); Google News (News);
Froogle (Froogle); Google
Local, which used to be called Google Maps (Local); and Google
Desktop (Desktop). There's also a more link, which is covered in some more detail. In
addition to these links, to the right of the search box are links to Advanced Search (for doing an advanced search), Preferences (which enables you to change your Google
preferences), and Language Tools (which enables
you to search through pages written in specific languages, and also includes
language-translation tools).
Google prides itself on its barebones interface, so it's
unlikely that you'll see many more links than what you see
here on the front page. But this minimalist interface leads
to a conundrum: As you'll see in this book, there are many more Google tools and
services than there are links on Google's front page. In fact, this book doesn't
cover all the tools and services that Google has because there are too many. So
how do you find out about a tool or service, or even discover which ones
exist?
That's where the more link
comes in. Click it, and you'll see the More, more,
more page with the current, comprehensive list of all Google's tools and
services. So to get to any of these available features, head to the More, more, more page. For a description of the main
tools and services here, see this book's Appendix.
A few links of note are on the page. The web search features link is a
great place to go if you want to use Google's many specialized searches, such as
for package tracking, stock quotes, music, and more. And the
Labs link is the place to go if you want to see
what new features Google is cooking up in its labs. New Google tools and
services start here. Some experiments don't see the light of day, while others
go on to fame and glory.
