Oral history, if recorded and carried out properly, can give insight into history in ways written history cannot, giving the public a more up-close, personal take on different matters. However, we are only humans living in a non-perfect world; we make mistakes, therefore there are errors in our documentation throughout time.
Oral history has the potential to be accurate, but it is only possible in a perfect world, which we do not live in. An oral resource has the potential to be reliable, if the information is handled properly. Facts from sources can be passed from source to source if remembered and recorded word-for-word. If left untampered, the information from this source can provide useful information for years to come.
Oral history may be less accurate then closely studied written history, but it adds a different element and perspective to history, somewhat like blogging. The information is passed straight from the source to the public, with little-to-none editing inbetween. This adds a more personal perspective on matters, because it comes straight from the source studying the material. With information straight from a researcher, one gets a summation of all information, with a clear understanding of the difference between facts found and opinions created. Oral history may not transfer formerly, but the information is found through formal studies typically; if one wants solid information and opinions on a matter, they typically interview serious and level headed researchers. By passing their knowledge orally and word-for-word, there is no possible way of twisting words and information into something it is not.
Oral history, as inaccurate as it can be in comparison to written history, has potential to be accurate while providing a different dynamic on information and news that, at the time, were current events. By transferring the information from a researcher orally from source-to-source, in a word-for-word fashion, one can provide knowledge with a new interesting dynamic. Future researchers can look at past researcher for insight with little bias and a personal perspective and take on the matter.
