Documentation is a necessity as discussed in this class throughout the course. To acknowledge the source and from whom the work is being produced from is highly important. Hauptman discusses this is great detail. Footnotes are mentioned within this article the reasons of footnoting ,citations and the role they play in acknowledging the source on where the information is coming from. The issue of URL changes came up within this article which was very interesting. I have had questions regarding citations including URLs in the past in terms of changes and the URL being too long etc. Citations based on URLs can be a bit frustrating especially of the URL is too long. There are times where you would like to review the citations and check out the URL but the page wouldn’t come up. Resolving this issue can be a problem.
