Is a personal or organizational author identified?
Does the author provide contact information, e.g., e-mail address, telephone number, street address?
Does the personal author provide any credentials...
organizational affiliation?
education?
occupation?
years of experience?
Do the credentials suggest an inherent bias of particular point of view?
Is the author the creator of the document or a compiler of information resources?
Can you find other material by or about the author, either on the Internet or using library resources, e.g., reference materials or indexing publications?
