Make sure your list of references - your bibliography - is accurate and complete in all respects.  Even if you write a review of a single book, you should mention it in a bibliography at the end of your paper.  Many journals have specific guidelines for how references should be made – You should ask your professor which style guidelines he/she prefers BEFORE drafting your bibliography.  Such guidelines are usually published regularly in specific academic journals and are often found on journal websites.  Even though almost every academic journal has different guidelines, there are some very general rules for references that you should always follow.

Do not include any authors or works in your bibliography to which you do not directly refer in the text.

Make sure you include all works that you have cited.  If the reference is incomplete for some reason, find the necessary information and complete it.  If this is not possible, explain in the bibliography that the missing piece of information is not available (for instance use "nd" for "no date" or "ng" for "not given"). 

If an article you cite in your text is part of a larger, edited volume, your must cite the specific author, not the volume editor(s).  The complete information about the volume must be made in your bibliography.  Similarly, if there are more than two authors (Ruff, Trinkaus, Walker, and Lawson 1993:22), your specific reference may be shortened (Ruff, et al. 1993:22), but the full citation must be included in the bibliography.

If a work is reprinted after a significant lapse of time, both dates are given, e.g. 1993 [1924].  This information should also be mentioned in your in-text citation as well.

Bibiliographic references are listed in alphabetical order, references by the same author listed by year with the earliest first.  If there are several references are by the same author in the same year, they are alphabetized and distinguished by "a" and "b" after the year (as well as in the in text citation).
