Do not procrastinate. When you wait until the last minute to begin working on an assignment, you will feel rushed. Either you will fail to document the use of your sources accurately or you might make a poor choice and choose to simply "copy and paste" together your paper. Not a good idea. To avoid this potential hazard, start early. You will thank yourself later.
Get comfortable with your required/ often used citation style. The more you use your chosen citation style (MLA, APA, Chicago), the more comfortable you become with appropriately using it and documenting your sources accurately.
Keep track of your source materials. The best way to do this is have an actual copy of your source. Print out, copy the source, or save the electronic copy. It is much easier to work with paper material, than try to remember where you found a source. Anderson University Thrift Library provides both copiers and printing services.
Take good notes. Within your source material, highlight key passages and annotate the text in the margins. Just be sure you are doing this note taking in a copy of the source material--not highlighting in a library book.
Maintain a working bibliography. Essentially, keep a list of any sources that you consult or think you might include in your assignment. Make sure that in this working bibliography you note the important citation information for your source material (ex. title, author, publication information, URL, etc.)
Ask your librarian or professor. If you are unsure about how to cite source material or whether or not something should be cited, check with your instructor or librarian; they are the professionals.
