Differences
There are many differences, but a few similarities, between APA style and MLA style. APA is traditionally used in scientific, social science, and psychology papers. MLA is used in humanities papers. Both lists are double spaced, organized alphabetically, and have the second and additional lines indented (hanging indent). The main differences are listed below, but for specifics see each individual listing in the APA Publication Manual, 5th edition:

  MLA APA
