Constitute allows you to interact with the world’s constitutions in a few different ways.
+ Quickly find relevant passages. The Comparative Constitutions Project has tagged passages of each constitution with a topic — e.g., “right to privacy” or “equality regardless of gender” — so you can quickly find relevant excerpts on a particular subject, no matter how they are worded. You can browse the 300+ topics in the expandable drawer on the left of the page, or see suggested topics while typing in the search bar (which also lets you perform free-text queries).
+ Filter searches. Want to view results for a specific region or time period? You can limit your search by country or by date using the buttons under the search bar.
+ Save for further analysis. To download or print excerpts from multiple constitutions, click the “pin” button next to each expanded passage you want to save. You can then view and download your pinned excerpts.......
