A bibliography is a list of sources used and is generally found at the end of a work. While the term originally referred to books, a bibliography should include any source of information or ideas. Modern bibliographies might include journals, websites, movies, and even e-mails or discussion board postings.
Each bibliography entry has enough information - work title, author(s), publication date, etc. - so the reader can consult that source later. While an entry about a website will have some different information than one about a book, all entries look similar because they are formatted in one particular style such as MLA or APA.
