Some bibliographies are for the use only of the writer. Others are meant for use by students and scholars. Organizing and retrieving information for use in one s occupation and personal life is increasingly necessary. Bibliographies offer a way of organizing. If stored electronically, information can be searched and manipulated for many uses.
Enumerative bibliographies are just lists of citations.
They list everything available on a topic in a given timespan, journal, library, etc. A standard bibliographic format suitable to the subject or discipline should be used. Other recognized styles may also be used. Annotated bibliographies include notes about the items. Clear concise writing is desirable.
