APA Style is an editorial style developed by the American Psychological Association and used for written materials in the social and behavioral sciences. APA Style requires you to cite the sources you have used in two places: the in-text citation and as part of your reference list at the end of your paper.

To create one yourself, you need to know a few pieces of information about your source and then follow the examples from the APA Quick Reference Guide or Purdue Online Writing Lab's APA Formatting site to format your reference.
