Which would be the least credible source of information for Zack to use for his essay on national forests?

A website with no identified author is the least credible source because Zack cannot check who created the information or assess that person’s expertise. A textbook chapter, newspaper article, and book generally have identifiable publishers or authors and editorial review. Therefore, NationalForests/AGlance.com is the least credible choice.
