You can continue to browse through the groups (or search), and when you find a group you are interested in, read or wade through the postings In order to start a Usenet group, post to a Usenet group, or bookmark a Usenet group, you need a Google account (I explain getting a Google account in 6 and 14) and a Google Groups nickname You do not need to log on to browse or read discussions To make dealing with the volume of posts on Usenet easier, Google organizes posts in reverse chronological order and by thread a post with all the follow-up posts that replied to, or commented on, the original post Although using Google Groups is likely to be more a recreational activity than a research activity, in some circumstances if you want to know what people are saying about something Google Groups can be a valuable research resource

Introducing Google Images Limiting image search results using your criteria Incorporating pictures into your research Organizing pictures with Picasa

oogle Images is a Google service that lets you use Google s search tools to find pictures photographs and other graphic images on the Web

In this chapter, I show you how to use Google Images to pump up your research results Along the way, I show you how Google Images works (you may be surprised) and explain why this tool can be so important to providing wellrounded, high-quality research results I also show you how a neat Google tool called Picasa can help you organize the pictures you already have saved on your computer

Because nearly one billion images are floating around on the Web, finding the picture you need for your research can be pretty tricky Google Images helps you manage this difficult feat In the following sections, I explain what Google Images does and how to use Google Images effectively

page surrounding the image, the content of the alt HTML parameter associated with the image, and (most importantly) the caption of the image are the essential clues Google uses to categorize and sort image search results Using contextual analysis, Google Images does a surprisingly good job of understanding what an image depicts Of course, Google Images can t always do a perfect job, and if the contextual elements aren t present perhaps an image is placed alone on a Web page without any text at all Google has no way to determine the content of the image Google does not consider the filename of an image when analyzing what the image is So if you have a photo named billclintonjpg on a page by itself, Google won t know that the picture is of Bill Clinton

You have your choice of a number of ways of opening the Google Images application: Type imagesgooglecom into the Address Bar of your browser and click the Go button (or press the Enter key on your keyboard) If you have installed the Google Toolbar (as explained in 1), click the Google button to open the fly-out menu; from the menu, choose Google Links Google Images On the Google home page, click the Images link On the Google home page, click the More link; when the Google Services and Tools page opens, click the Images icon or link The Google Images home page is shown in Figure 8-1
