The Bodleian Libraries subscription to HeinOnline now includes a collection called “Slavery in America and the World: History, Culture & Law”.
This HeinOnline collection brings together, for the first time, all known legal materials on slavery in the United States and the English-speaking world. This includes every statute passed by every colony and state on slavery, every federal statute dealing with slavery, and all reported state and federal cases on slavery, as well as thousands of pamphlets, books, legal commentaries, journal articles, and modern histories of slavery. Full details of what the collection contains may be found on the HeinOnline website.
The collection is contained within HeinOnline, which may be accessed via SOLO or OxLIP+. Once through to the HeinOnline database, look for the collection in the Browse Collections list.
