An annotated bibliography can vary, so make sure you know your teacher's instructions. The basic idea is that it's like writing a Works Cited page, but including an annotation, or detailed paragraph, about each source on the list. What needs to be in the note depends.
To make an annotated bibliography is not an easy task, as you well know. I suggest that you leave this to the end. Also this presupposes that you know the field decently well. Also you might want to read a book that deals in generalities of your field. A introductory book can be your best friend with the need for an annotated bibliography.
One of the easiest ways to cite sources is done automatically on Windows 2007. On the toolbar, you will find the different styles such as Chicago, APA, MLA, etc. If you have access to this, you can click on the appropriate one and type in the information. The program will automatically arrange the reference for you.
A helpful site is www.citation.com which will assist you by providing examples and models for you to follow. Of course, these will not provide you with descriptors, but they will make arranging of titles, etc. much faster.
Your first task will be to determine which research paper style your teacher will require. Most English classes follow the MLA style. You can buy an MLA handbook or look up MLA guidelines on the internet.
The difference between a bibliography and an annotated bibliography is this. A bibliography is a list of research sources, such as books, articles, and interviews. An annotated bibliography lists the research sources, but it also includes a short descriptor for each source indicating its scope, content, focus, etc. The purpose of the annotation (descriptor) is to guide researchers in locating sources that address their research needs.
