If you require use of a different style guide, contact me for information on other available resources.
Note: Some resources below refer to the new APA 7th edition Publication Manual, some refer to APA 6th edition. Check the edition of the resources before consulting.
Reference managers store, organize, and properly format references for citation in your papers. They also generate bibliographies.
Some are commercial products requiring purchase or annual subscription. Others are available for free.
