Rezumat	Triangulated in-depth interviewing applies Denzin's triangulation logic to the in-depth interview method by deliberately combining multiple sources of convergent evidence — different informants, interviewers, time points, or corroborating data types — to strengthen confidence in qualitative findings. Rather than relying on a single interview account, the researcher gathers rich, open-ended accounts from several vantage points and cross-checks them for consistency and divergence, treating agreement as corroboration and disagreement as analytically meaningful.	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.
