Evaluative annotations (also known as "critical" annotations) summarize the key concepts in a text and make judgements about their quality (negative, good, or both). Your remarks should progress from textual specifics to your assessment of the source. You should never simply state that you are quoting or referencing a source; you must also comment on what that source says. For example: "The author of this passage was apparently not familiar with Aristotle's Poetics because he/she uses the term'mimesis' in its modern sense - imitation - when discussing how poets imitate things that happen in life." This annotation points out an error in an essay on Shakespeare's plays written by a student who has probably not read much English literature. It is negative because it reveals that the student has misunderstood something important in the original text; it is also helpful because it gives a specific reason for the misunderstanding. Evaluative comments can be either positive or negative. Positive comments praise the quality of the idea presented in the text, while negative comments criticize certain aspects of the text that need improvement. Comments should never be simply affirmative or negative, but rather they should indicate why you like or dislike something about the source.
