Sadly nearly all of these post contain factual inaccuracies.
Reliability speaks to whether or not a source can be trusted. We determine this through perspective.
Who has written the source? (Do they have reason to lie? Could they be bias? Are they to be trusted)
What have they written (Are they using emotive language? Are they commenting on official proceedings? Is it an opinion? Is it an official document such as a policy?)
Why have they written it (Are they trying to speak to a specific audience? Are they attempting
Where does it come from? (Can we trust the source? Is it propaganda? Does it come from a government with reason to lie to the people? etc)
When was it written? (At the time? Years after? Can this muddle a persons perspective?)
How is the source presented? (is it a memoir? is it primary? Is it a official document? Is it secondary? is it written? Is it a picture? Is the author trying to persuade?
To establish reliability you need to look at the validity of a source. Contrary to what has been said a subjective source is not a reliable one. In establishing reliability what we are really doing is saying... on the whole we are able to trust this source. All you need to do is apply the criteria to the source... If you answer all the above questions you then have a basis to argue for or against its reliability.
As for usefulness, reliability and usefulness are not mutually exclusive (you can have a reliable source that is not useful and a useful source which is not reliable) and not every source is useful. Why???
You are never asked the usefulness in general. You are always asked about the usefulness RELATIVE to a historian studying a particular thing. Also, the type of source can effect its usefulness..
For example, you may have a source which is a drawing of the Christmas truce by a commissioned British artist. You are asked if it is useful to a historian studying the mental condition of troops on the front.
You can argue this source is not useful. It gives no real insight into soldiers were really feeling. It was not painted by a soldier. It is an artists impression. He had not experienced what was going on on the front from teh perspective of a solider. He was simply giving HIS impression.
The source would be useful for example if the Historian was studying the commission of artists for propaganda purposes... but not to the mental condition of the troops....
