Contain mainly qualitative data that expresses the beliefs and meanings held by individuals and organisations
Some are contemporary, others give historical perspective
Interpretivists
Seek to discover the meanings that underlie our actions and this means using open-ended research methods that produce valid, qualitative data
Interpretivists regard documents as high in validity because they are the freely expressed meanings of those who produce them
Positivists mainly reject the use of documents because they consider that they lack reliability and representativeness
Positivists may make use of the statistical data contained in some documents, or may convert the qualitative contents of documents into quantitative data by using content analysis
Personal documents
Diaries, memoirs, autobiographies and letters created by individuals for a variety of uses
Advantages of personal documents
Mostly written for personal purposes, often have a fairly high degree of validity and provide a genuine insight into people's attitudes
Mostly cheap and save the researcher time, although accessing them is not always straightforward
Disadvantages of personal documents
May have many problems that can make it difficult to evaluate their validity
Some groups (e.g. the illiterate) are unlikely to produce them and so their views are not represented
Some are created after the event with the benefit of hindsight
Written with an audience in mind which may affect what is recorded, and personal bias is likely to be present
Public documents
Produced by bodies such as government, business, the media and voluntary organisations
Advantages of public documents
Often plentiful, detailed, cheap and easy to access
Disadvantages of public documents
Content is likely to be selective and presented with a particular bias, as the authors are aware that the documents are publicly available
Historical documents
The only way in which we can study past societies, especially if there are no longer any survivors whom we could question
Disadvantages of historical documents
Meaning of words changes over time, some may be lost or destroyed, giving an incomplete and unrepresentative picture of the past
Content analysis
Quantitative - measures the amount of coverage given to a particular issue
Qualitative - examines the meanings attached to particular words and images
Tests of documents
Authenticity - Is it genuine? Is it what it claims to be?
Credibility - Can we believe the document and the sincerity of the author?
Representativeness - How typical is the document of a wider social group?
Meaning - Can we interpret the author's meanings correctly?
