You will find it easier to prepare your final bibliography if you keep track of each book, encyclopedia, or article you use as you are reading and taking notes. Start a preliminary, or draft, bibliography by listing on a separate sheet of paper all your sources. Note down the full title, author, place of publication, publisher, and date of publication for each source.
Also, every time a fact gets recorded on a note card, its source should be noted in the top right corner. (Notice that in the sample note card, The World Book, Volume 2, page 21, has been shortened to: WB, 2, p.133.) When you are finished writing your paper, you can use the information on your note cards to double-check your bibliography.
When assembling a final bibliography, list your sources (texts, articles, interviews, and so on) in alphabetical order by authors' last names. Sources that don't have authors (encyclopedias, movies) should be alphabetized by title. There are different formats for bibliographies, so be sure to use the one your teacher prefers.
