Gather your research materials. Include anything that you used for information to write your paper or book.
Write about the author of your first source in the beginning of your first bibliography entry. Include the author's name, professional title, qualifications in the subject area and his profession. For example: "John Doe, author of 'Bibliography Examination' and an English professor with a Master's Degree in English Literature, provides an in-depth look into the two types of annotative bibliographies."
Write the second statement of the entry as an explanation of the author's intent for making his main point in the reference material. The statement should reflect why the author wrote the reference piece and should touch on just the essence of the main idea. For example: "In this informative piece on bibliography types, the author explains the difference between summative and evaluative bibliographies."
List some of the important pieces of information that the author used to support the main idea in the reference material. This statement should supplement the main idea that was presented in the previous statement. For example: "Evaluative bibliographies go into the reader's subjective description of the reference piece, while summative bibliographies are made up of only facts."
Write the final statement as a conclusion to wrap up the entire entry with a sentence or two about how the supportive pieces of information from the previous statement tie-in with the main idea. For example: "John Doe explains that the two types of bibliographies are separated by personal views of the reference material in the entries of evaluative bibliographies."
