History and humanities collects references, archives, and projects for the study of people and the past. Listings include philosophy and economics references, digitised archives, museum collections, historical atlases, and course material from universities. They differ in what they give you, since some are primary sources you can read directly while others are summaries written for a general audience. Compare who wrote or compiled each one, what period and region it covers, and whether it cites its sources. Where a claim matters, follow it back to the source document before you repeat it.
