In the old days, when you cited sources, one had to do it all by hand, writing down the citation, making sure it was properly formatted, and keeping things organized. It took forever. But nowadays, there are oodles of online tools that make keeping track of and citing your sources easy as pie.
A bibliography is a list of sources that relate to the content in a research paper or project. You can find examples of bibliographies in the final pages of some nonfiction books. Authors sometimes include a list of sources for further or additional reading. This additional reading list is a bibliography.
A works cited page is a list of sources that are included in the body of a research paper or project. When a quote or piece of information is added into a project, the writer includes the in-text citation or parenthetical citation. This is the last page of an MLA research paper.
