Knowing these helps to define the trustworthiness, the significance, or the importance
of the conclusions reached in the article. It can also signify the slant, focus
or bias of the article. There should be some indication with the article, i.e., university
or research affiliation, or company. Look for any clues at the beginning or end
of the article. The usual places for author notes are footnotes on the first page or
after the end of the article before the notes/bibliography or reference list. In some
journals or collections they’ll be in a separate section which might not have been
copied with the article.
