A footnote is used to identify the source of quotation and acknowledge the use of words or ideas borrowed from published or unpublished sources. All words taken directly from a source must be footnoted. Footnotes are placed in parentheses within the text, at the bottom of the page on which they appear, or at the end of the paper. A bibliography is a list of all sources consulted or used in the preparation of a paper, including books, articles and non-print materials. The basic differences between these two forms of bibliographic citation are in indentation, the order in which the authors' names are written, and completeness.
Footnotes refer to specific passages or pages, while bibliographies cite an entire work.
There are many different styles of bibliographic citation. The important thing is using a consistent style of presentation and documentation throughout your research paper.
