This page is the map to the sources behind the site. It shows which kinds of evidence OZJF trusts most, and on which kinds of questions.
Primary sources first
For legal, diplomatic, or institutional questions, start with the record itself. That means a treaty text, a designation list, a statute, a court document, an archived statement, or an original poll release. These sources are not perfect. They are where the public record begins.
Secondary sources still matter
Primary material is not always enough. Historical meaning, comparative context, and institutional background often need strong secondary analysis. So OZJF draws on Congressional Research Service reports, archival diplomatic summaries, peer-reviewed reference works, and trusted research institutes when they are the best available layer.
What this page helps readers do
Use this page to see why one source was picked over another. Use it to find the kind of source that should settle a disputed fact. Use it as a starting point if you want to challenge a page on evidence grounds. A credibility-first site should make that easy.
That means poll pages should rest on original releases and public disclosure norms like those from AAPOR and Pew Research Center. Diplomatic and historical pages should rest on the original texts or strong documentary records. Those include the State Department’s Office of the Historian and nonpartisan CRS products. The point is not to sound academic. The point is to tie each page to the strongest evidence we can find.
