• Archival references. Archival references are published references that the library could get if you asked them to.

• URL's (Web addresses). Web pages are no substitute for archival references. There is good, reliable information on the Web, and there is garbage. Even the reliable information may not be there tomorrow. If all of your research was done over the Web, you have done an inadequate job.
