Documents
Documents are a secondary research method where you analyse existing materials like letters, articles, or policy documents. These can be historical, personal, or official documents that give you insights into social phenomena.
Practically, documents are fantastic - the data already exists, so it's quick, cheap, and easy. The challenges come when documents are damaged, in foreign languages, or when you need to interpret what the original author really meant.
Ethically, it's mostly straightforward since you're not directly involving people. However, you might need to protect the author's privacy or get permission to use their work. Theoretically, documents provide valid and representative data, though analysing old or foreign language documents can be properly challenging.
