A bibliography is an alphabetical list, by author, of the sources (books, journals, websites, etc) you have used to research and write your assignment. A bibliography usually includes information such as the author, title, publisher and date. An annotation is a concise summary and/or evaluation of the value or relevance of each source. An annotated bibliography combines these two elements and provides bibliographic information plus a summary and/ or evaluation of each of the sources you have used. An annotated bibliography may be one part of a larger assessment item.
