Notice that since I took a direct quote from John Smith's book, I placed those words in quotation marks. Notice also that I placed the date that the book was published directly after the author's name in parentheses--this is proper APA format. Finally, notice that because I explained WHO wrote the book and WHAT book it comes from, the reader is easily able not only to find the source on his/her own to check my facts, but the reader is also more likely to believe what I have to say now that they know that my information comes from a credible source.
If you’re a student, your schoolwork won’t go through this whole process before it’s finalized. Your paper is considered “final” when you submit it to your professor. For example, a dissertation, once submitted, becomes the final, published version of record. Therefore, it’s important to consider the final appearance of your paper during the draft stage. Some formatting issues not covered in the Publication Manual will need to be addressed while you’re writing your paper. When in doubt, always check with your professor or university to see if they have their own preferred standards.
