Are citations already in APA format?
I hope I understand your question correctly. I am assuming that what you want to know is whether the citations that you copy and paste from an on-line source are already in APA format. The answer is that sometimes they are, and sometimes they are not. If you are using EBSCO, for example, you can choose the format as APA, MLA, or a few others. There is a box with choices. I do not recall what the default choice is. But otherwise, I do not think that you should count on the format being correct for APA. Since so much writing in college must be in APA or MLA, the best thing you can do for yourself is to master both forms of citation. Writing with either becomes much easier when you do it all the time!
Let me add to the previous post by saying that the citations on enotes that I have seen are all in MLA format. One of the quickest ways to tell APA from MLA is to look for the year of publication. In APA, the year is given early, after the author's name. In MLA, the year appears at (or, in the case of internet sources, toward) the end of the citation.
The previous poster is absolutely right. The citation styles are easy enough to learn, and learning them will make that one part of a student's life a whole lot easier.
