Finding Parliamentary Papers

  • Understand the technical context — How does it work? Consult the documentation (and the TDG!) to understand your options.

  • Be creative and strategic — Solve your puzzle by experimenting and looking for clues in the results.

  • Stay critical — Always assume that Trove isn’t telling you everything.

Search is a research method
