Also, see if it presents a balanced view. A print version of Ulrich's is shelved behind the Information Desk in the Library. Information may be published by an association, a university press, a commercial publisher, a government, or even an individual. If you know something about the publisher, you can often identify bias and point of view. Many Internet sources are not reviewed before being posted.
Some websites review the pages they link to.
You will tend to find more reliable information if you choose sites from the Librarian's Index to the Internet , the HSU Library Subject Guides , or other such sites. Another section of this OWL has more information on evaluating web resources. Read a critical review of a book or recording. Read or skim the source. If it contains too much technical or specialized language or if it is written for experts in the field, you may wish to choose another source.
