To annotate is to just add a notation that will add to your paper in some way or clarify a point. It adds to the understanding of the reader. For example I'm reading an autobiography of Helen Keller and at times she talks about someone in her life that was probably well known back in her time but not now. So there's often an annotation letting me know to whom she's referring.It means to highlight the important information and take notes on them. Also, highlight the words that you don't know, look them up, and write down (next to the word(s)) what it/they mean and to to give credit for your sources of information in an essay, term paper, etc. like a footnote (for this, put author's name like it should be--John Smith, etc.) or in the bibliography at the end (author's name--reversed in the bibliography so it can be put in alphabetical order; name of publication, novel, article, etc; city where published, publisher and date; and pages used. EXAMPLE: without quotes, however
" Smith, John. My Life (underline titles). New York, NY: Penguin Publishers, 1995; pp. 1-25." its now possible to annotate documents online through a.nnotate its fast and its easy! do visit their site for info.
