Final answer:
For each piece of source information in an essay or research paper, 2-3 sentences of commentary are typically needed to analyze and explain the evidence in the context of the argument. An annotation usually consists of one to two paragraphs, with 100 to 200 words considered a standard length.
Step-by-step explanation:
When incorporating source information into an essay or research paper, one must ensure that the commentary provides a thorough understanding of how the source information supports the argument. A generally accepted approach involves using a graphic organizer to arrange your notes, which assists in the creation of comprehensive annotations. These annotations start with a brief summary of the content, followed by a discussion on the source's unique features, an evaluation, and a reflection on the relevance of the source to your research.
For each piece of evidence used in your writing, it is recommended to provide at least 2-3 sentences of commentary that analyze and explain the evidence. This ensures that the reader comprehends not only the evidence presented but also its significance in the context of your argument. Keep in mind that while writing annotations for an annotated bibliography, descriptive/informative annotations are simpler, and analytical/critical annotations provide deeper analysis.
Annotations may vary in length depending on the depth and complexity of the source material, but a standard annotation often consists of one to two paragraphs, or approximately 100 to 200 words. The balance between your own ideas and the information from sources should be mindful, maintaining a healthy ratio where your original thoughts and analysis remain the forefront of your writing.
