You will be asked to comment of the usefulness of 2-3 sources to a historian undertaking A PARTICULAR HISTORICAL INVESTIGATION.
You should make the following notes on your source booklet as soon as you start this section- having read them and mentally thought about all this during your reading time:
Indentify the TYPE- is it a poster? personal letter from a German soldier? personal letter from a British officer? Speech made to British Parliament? Photgraph?
Once you identify TYPE there are a whole stack of implications that you need to bring into your response, without going into content in any depth at all. The purpose of this question is not to comment on content, it is to show you have got your head around HOW the "content" of the source came to be
eg
A PHOTOGRAPH of women at work in a factory in Britain in 1917 could be deliberately POSED with the express aim of inspiring women to contribute to the war effot and normalising this major change in society. If the photograph was produced by the government, this would be highly likely. You would expect an official photograph to show clean, healthy, happy female workers in good working conditions. This contrasts with the reality of working conditions in factories in Britain where women were subject to poor working conditions and health problems (such as TNT poisoning in the case of munitions workers). This will not be evident in the photo, but you WILL have that knowledge- so that is an example of showing your knowledge AND showing you are analysing the photograph.
TYPE is the starting point for source analysis. Once you identify tyoe you then automatically start to run through author, context, motive, audience and the other requirements of the question.
ALWAYS remember to tie your analysis back to the specific historical investigation under consideration- a source that is useful for one area of investigation may not be as useful for another, because of the limited perspective it offers, unless it is used in conjunction with other sources
eg
The photograph of women etc described above may be useful for an historian investigating government propaganda in Britain, but not as much for investigating women at work in Britain in the war.
