Carnegie Mellon Libraries:





Why is this important?
  • Some topics aren't covered as well on the web as in books or periodicals.

  • Many web sites are never finished or updated.

  • It's always best to find the most complete web sites on your topic.


How to evaluate it
  • Does it meet your purpose?

  • Are you looking for an overview or for analysis in depth?

  • Is the topic covered adequately and in sufficient detail, including names, dates, places, and events?

  • Is the information original, or just a rehash of someone else's work?

  • Has the web site been finished, or is it still a "work in progress?"

  • Has the information been updated?

  • Is the data complete?

  • Does the site have a geographic or other limiting focus?

  • Is there a fee for access to the complete web site or document?


Examples

1. Accounting Standards

Although it takes a few minutes to understand this site, it is very complete:

It is published by the official issuer of the standards.

Contents are clearly defined.

Instructions are given for finding changes to the original standards.



2. Conformity

If you were writing a paper on conformity, how useful would this page be?

Is enough information provided?

Is the information original?

Are suggestions for further reading provided?


3. Korea

The author of this site explains that some information is incomplete.

But he doesn't say exactly which information.

Ask a reference librarian to recommend a reference book that has complete coverage.


4. News

Many newspapers and magazines (like the Wall Street Journal) tempt the reader with partial information.
The complete story requires a fee.

You can get the full text of many of these newspapers and magazines through a library database such as Lexis-Nexis Academic or Proquest Direct.
No fee is required.


5. Periodic Table

Coverage of the elements at this site is excellent.

Read through the notes to find out more about the project.


6. Walt Whitman

The Bartleby site has useful features:

  • Table of contents

  • Keyword search

  • Index of titles

  • Index of first lines

  • Link to the bibliographic record for the book that was digitized

It's still hard to tell whether these are the complete works of Walt Whitman.
