AltaVista's Photo Finder
The AltaVista Photo Finder helps you find millions of colorful and imaginative pictures from the World Wide Web. You can choose a filtered or unfiltered search. This is very helpful when trying to locate images on the web.
WebWhacker is an advanced off-line browsing tool that allows you to re-create sections of the World Wide Web directly on your hard drive or local network. You can save particular pages--complete with text, links, graphics, Java applets, sound clips, even video clips if you have sufficient hard drive space. Once the Web pages are saved to your hard drive (that is, once you have "whacked" them), you can refer back to the information and clips at any time, without an online connection and additional connection charges.
Evaluating Web Info
So you have found the answer to your query- How do you know that you can trust it? Is it from a reliable source? What are some techniques I can apply to the information to judge its worth?
Criterion #1 Accuracy
Is the information reliable and free from error? Are there editors and fact checkers or "gatekeepers" for the info? Are reliable and checkable sources quoted? Is it true to reality?
Criterion #2 Authority
What are the author's credentials or qualifications for writing on this subject? Are they given? How reputable is the author/publisher? To what level is the information self referential? Are other resources cited?
To what extent is the information tryng to sway opinion or convince you? Is the information presented with a minimum of bias? Is this just a "virtual soapbox"?
Criterion #4 Scope
What topics are included in the work? To what depth are the topics explored? Is the information one inch deep and a mile wide?
Criterion #5 Currency
Is the content up to date? Is the publication date clearly labelled? Does th information reflect familiarity with current research?
While the strength of the web is its capability to publish dynamic and up to date information, its weakness is the absence of resources that have long been considered master resources for researchers. One sees citations to other sites that in turn cite the first source. Go to the library if you run into this issue.
