What type of information should not be included in the reference list?

The correct answer indicates that sources which were consulted but not cited in the text should not be included in the reference list. In APA format, the reference list is specifically intended to provide a comprehensive list of all sources that are directly cited in the document. This means that for any source listed, there must be a corresponding citation within the text that clearly indicates the author's contribution to the work being presented. Including sources that were not cited could lead to confusion about the relevance of those sources to the content of the paper and mislead readers regarding the author's direct influences and findings.

On the other hand, works that are actually cited provide direct support for the claims and arguments made in the text, and academic journal articles and books referenced directly provide crucial context and credibility to the research presented. Therefore, they are appropriately included in the reference list.
