Searching quantitative data for historians: 2. How to reuse datasets

Conditions for reuse

When a dataset is available online, it doesn’t mean anyone may share or reuse it without conditions. Check the terms of use or the licence. Creative commons licences are widely used. The most open Creative Common licence is CC0 (CC zero), but the author is free to put restrictions on sharing and reusing the dataset: they are ordered here from the most free to the least free licence.
