If you are writing a paper for a psychology class, your instructor might also require you to write and submit an APA format bibliography. A bibliography is an alphabetical list of all the sources that you might use to write your paper. It is similar to a reference section, but there are some important differences. While the reference section is composed of all the sources that you actually cited in your paper, the bibliography also includes any sources that you considered using.
If your instructor does not require a bibliography, you might want to think about creating one as a way to help organize and keep track of your research. Once you are finished writing your paper, it will be much easier to simply look back through your bibliography in order to create your final reference list in proper APA format. When you do use a source in your paper, you simply need to include an in-text citation and add it to your references page. By doing this, you will save yourself the hassle of going back to figure out where the original sources of your citations came from.
In some cases, your instructor may require you to create an annotated bibliography. This differs from a normal bibliography in that each entry contains a brief summary of what the source was about. In some instances, the annotation may only be a sentence or two long. In other instances, your instructor may require you to write an entire paragraph for each entry.
