Sammanfattning	Triangulated document collection is a qualitative data collection strategy in which documents from multiple independent sources are gathered and cross-checked against one another. By drawing on different document types — such as official records, personal archives, institutional reports, and media artifacts — the researcher reduces reliance on any single source and strengthens the credibility of the evidence base. The approach applies Denzin's data triangulation principle directly to documentary material.	Content analysis is a systematic research technique for reducing text, visual, or media material into coded categories so that patterns can be counted, compared, and interpreted. Formalised by Klaus Krippendorff in his widely cited methodology textbook (latest edition 2018), the method sits at the boundary of qualitative and quantitative inquiry: it imposes structured, replicable coding on inherently meaning-laden material.
