NetResearch: Finding Information Online
Preface / Chapter 1: Instant gratification...and beyondFrom the Preface
This book teaches lasting skills
Many of today's "Introduction to the Internet" books discuss Net searching, particularly on the World Wide Web, in a strange way. Like cookbooks, they provide step-by-step instructions for locating particular Web pages. Some books, in fact, are just big lists of Web sites: so-called Yellow Pages of the Internet. The problem with this approach is that the Internet changes rapidly. A year later, or even by the time the book goes to press, many Web pages have moved or disappeared, and the book becomes out of date--about as useful as an old telephone directory.This book, however, is built to last. It's not just a big list of Web pages (though we do include one as an appendix to help you get started). Instead, it teaches general strategies and search techniques that will continue to work even while the Net changes around us. Can't find one of the Web pages listed in another book? No problem. We'll show you where (and how) to look next.
In short, this is how the experts do it. Not by memorizing lists that go out of date, but by gaining intuition.
This book has several parts
Every chapter ends with a quiz to test your mastery of the material. For instance, you'll be challenged to locate information on a particular topic or to discover somebody's electronic mail address. Some questions will have one right answer, but others will have several depending on how you search.
Chapter 1: Instant gratification... and beyond
The Internet is filled with information.
The Internet is one of the world's largest sources of publicly-available information. Thanks to the growth of the World Wide Web, millions of electronic resources around the globe are at our fingertips. To help us deal with this incredible amount of data, a new skill has arisen: Internet searching. Given any topic--mutual funds, plane schedules, beer, harpsichords, or whatever--anyone with an Internet-capable computer account can search the Net for information on that topic.Searching, however, is not the same thing as finding. The Internet is like a huge blob of facts, opinions, stories, conversations, arguments, artwork, mistakes, trivia, and one-of-a-kind knowledge. There's little organization or consistency. And yet, it's possible to navigate the Net effectively and reap great rewards.
This chapter provides a quick introduction to Internet searching: both its benefits and its difficulties.
You can search the Internet.
Assuming you have an Internet-capable computer account, let's jump-start this book with a quick example. (If you don't have an account yet, just follow along.)Run your Web browser (see the sidebar "Connecting to the Web" if you need help with this) and connect to Yahoo, a popular site on the Internet. Yahoo is a special kind of Web site called a search engine. If you type a few words onto the Web page, Yahoo attempts to locate other Web pages related to your words.
We'll connect to Yahoo by providing its Web address--called its "URL" (Uniform Resource Locator)--to the browser. This is generally accomplished using the browser's Open, Open URL, or Get URL command. When prompted for a URL, type http://www.yahoo.com.
If all goes well, you'll soon see Yahoo's main Web page.
Hmmm..., what shall we search for? Let's look for information on one of the world's greatest searchers: Sherlock Holmes. In the space provided by Yahoo, type the words Sherlock Holmes and press the on-screen Search button.
A moment later, Yahoo should respond with dozens of "pointers" to further information about Sherlock Holmes: tributes, lists of stories, Holmes t-shirts, Holmes museums, the life of Sir Arthur Conan Doyle (his creator), and more. These pointers, called links, lead to other Web pages. To follow a link, select it with your mouse, and its associated Web page will appear, containing information and more links. You can then follow those links to still more Web pages, and so on, and so on. Follow some links and see where they take you.
Welcome to the World Wide Web. As you can see, it wasn't very hard to locate tons of information about Sherlock Holmes. There must be more to searching, however...or else this would be a very short book.
Unfortunately, some searches fail.
One reason our Sherlock Holmes search succeeded so easily is that our goal was very general. Any information on Sherlock Holmes was good enough. Suppose you had a more specific goal: the name of a Sherlock Holmes story you read a long time ago. All you remember is that the victims were killed by a poisonous snake. So you might try asking Yahoo to look for "Sherlock Holmes and the poisonous snake".This time, unfortunately, Yahoo responds "No matching Yahoo sites." In other words, Yahoo didn't find anything that matches your goal. The search has failed.
Does this mean there's no information on the whole Internet about Sherlock Holmes and poisonous snakes? No, all it means is that Yahoo couldn't find what you requested. Maybe your request could be stated differently: for instance, by typing poison instead of poisonous. Or perhaps Yahoo is the wrong place to look.
Searches can fail for other reasons too. Suppose you need to know the definition of a word, so you decide to find a dictionary on the Net. You tell Yahoo to look for dictionary. In return, you get hundreds of links: a Japanese-Danish dictionary, a dictionary of famous quotations, the "Devil's Dictionary" by Ambrose Bierce, a genealogy dictionary, an English-Romanian dictionary of proverbs, a rhyming dictionary, a nutrient dictionary from a vitamin manufacturer, a dictionary of railway terminology, ...! There might be a traditional dictionary buried in this pile of data, but who has time to look? Sometimes, too much information is just as bad as too little.
In general, a variety of problems can occur while searching on the Net:
In other words, searching can sometimes be quite a challenge. Despite what media pundits may say about the information treasures of the Internet, some work may be required to locate what you need online.
This book is designed to teach you to be an effective Internet navigator, seeking out information, locating it rapidly, and avoiding pitfalls.
(Incidentally, the Sherlock Holmes story mentioned above is The Adventure of the Speckled Band.)
Searching the Internet is an art.
Do you know somebody--perhaps a friend or coworker--who always finds great stuff online? Have you ever wondered how he or she does it? Chances are, the answer is a combination of experience, insight, and perseverance. (And probably a little luck.) It takes a certain outlook to become a successful Net searcher, and throughout this book, you'll find some important themes that reflect this attitude.I call these themes the Internet Searcher's Rules for the Road.
- Carefully choose a starting place. Like the old saying says, sometimes "you can't get there from here." Different starting points may lead to different results.
- Don't assume failure too quickly. When a search program responds "nothing found," don't give up. Try a few variations on your search. If these don't produce results either, you can still try other starting places, programs, and search techniques.
- Don't assume success too quickly. Even when you locate what you need, there might be another source of information available that is better. Don't be too loyal to one Web site or one search technique. Keep an open mind. Experiment.
- Think about your route. Even if you reached your goal, there might have been a faster way to get there. Pay attention when a search strategy provides quick results: the same strategy might be usable in other situations.
- Know your tools. Read the manual. Use the online help. Try out all the commands and options. Make sure your search software is the latest version, or at least a recent one.
- Intuition is your best search tool. The Internet changes rapidly, and so does the software we use to access it. Knowledge, on the other hand, accumulates. As you learn from experience, you'll get progressively better at tackling new situations.
Net experts use these principles to locate what they need in the ever-changing online world. And when you've finished this book, so will you.
Accuracy isn't guaranteed online.
The Net can be a terrific source of information... or misinformation. Just because something appears on a Web page doesn't make it true. Material on the Internet is written by thousands of individuals with differing opinions, motivations, and levels of expertise. Since much of the material has not gone through any editorial process, you're bound to encounter errors, omissions, and biases online... even lies.How can you tell if an online resource is believable? This is a difficult task, similar to judging material you receive by postal mail, read in the back of magazines, or see on television "infomercials." Your best bet is to identify the source of the information, though this may be difficult. Your experience with the source will then determine how much trust you have in that information.
The URL (address) of a Web page can provide some assurance that its information is legitimate. If the Web page resides on a computer belonging to a relevant, official organization, this is a good sign. For example, a table of postal mail rates is likely to be accurate if found on www.usps.gov, the Web site for the United States Postal Service. (Chapter 6 will explain how to examine a URL and identify the computer containing the Web page, and from there, the sponsoring organization.) Web sites for major newspapers and magazines have the same credibility as their in-print counterparts, and well-known companies generally try to keep their Web sites accurate, though they may still use advertising hype. On the other hand, an advertisement for unproven health products, on a Web site you've never heard of before, that asks you to send money to a post office box, should be treated with extreme skepticism.
Some of the major issues of accuracy online are:
Nevertheless, the Net remains a great resource on countless topics. Don't be put off by this cautionary information. You just have to take some online "facts" with a grain of salt.
