Multiple versions of information on the Web often do more harm than good. On the other hand, it is easy to get so distracted exploring the Internet that you are no longer seriously researching your family. Be careful not to lose sight of your goals. Also, be sure to run a virus-checker on anything you copy to your computer. Sometimes, pages cannot be accessed directly, but only indirectly.
Private pages can change or vanish at any time.
For one thing, many Web sites require passwords or some other form of pre-registration. For another, the explosive growth of the Internet means that the indexing software is constantly struggling to keep up with the thousands and thousands of Web pages and E-mail addresses being added or modified every day. When your E-mail address changes, take a few moments to register the change on all the Web pages and databases in which it appears, so that others will know how to contact you. Since no single Web search is complete, it is a good practice to use two or more search utilities independently. Quality control on the Internet is highly variable.
