Imagine spending years, even decades, studying a culture. You collect notes, recordings, photos, and interviews. Then, years later, someone wants to check your work or build on it. But the data is gone. This isn't a fictional mystery. It's a real problem happening in a field dedicated to understanding humanity: anthropology.

This isn't about a single lost notebook. It's about a much bigger issue. Many older anthropological studies have data that is hard to find, incomplete, or simply missing. This makes it tough for new researchers to learn from the past.
