Primary sources present information in its original form, whether it be a work of literature or art or an account of an event. This information is stored in government-produced reference sources, monographs, and periodicals. The Internet provides access to the full range of information types, stored in networked computers around the world. Searching the Internet is like going to a flea market, in that you can find items of true value, but they are mixed in with items of little or no value. You can spend a great deal of time sifting, sorting, and selecting before you find something truly useful.
Bibliographies are lists of citations or references pertaining to a particular subject.
Found at the end of a book or article, bibliographies often include the most relevant and important sources. Understanding Citations Whether you are searching for information in indexes and bibliographies or citing sources in your own paper, you need to understand the conventions for documenting sources ranging from scholarly works to interviews. A bibliographic citation or reference should provide all the essential elements of information about the source to enable anyone to track it down. This includes the author, title, source and date of publication.
