Using sources is a kind of conversation, a scholarly conversation. When you read publications, you are engaging those authors in a discussion that is taking place in their absence. So, when producing your own publications (blog, paper, article, book, etc.), you need to recognize their contributions to your argument; and, moreover, allow anyone reading your paper to join fully in this exchange of ideas. In other words, your citations need to recognize someone else's ideas and to acknowledge what thoughts of theirs inspired yours.
Similarly, when reading others' work, their citations provide a way for you to follow their thought process as well as engage directly with the people with whom they have been consulting. In fact, sometimes the citations of a well-researched source can be more helpful than the content. So, do not just dismiss a source does not precisely address your topic. If their conversation overlaps with yours, check out who they have been reading. This is one of many reasons to search dissertations.
