Attention History Teachers:

Your dreams (some) have come true. You can have access to archives of primary source documents from Medieval History forward:

http://primary-sources.eui.eu/

The site is a “portal” which means you should expect to do a bit of searching to find what you want. You will be able to connect to a growing number of separate Web sites giving the actual access to individual documents.

The portal’s link to British History Online, for example:

British History Online is the digital library containing some of the core printed primary and secondary sources for the medieval and modern history of the British Isles created by the Institute of Historical Research and the History of Parliament Trust. Not all the primary sources offered from the XVI to the XIX centuries are delivered without subscription. You’ll find in British History Online, full-text editions of primary sources, such as the journals of the houses of Parliament or manorial records such as feet of fines; Printed guides and calendars of manuscript collections, such as the Calendars of State Papers; dictionaries and gazetteers of places, property, goods and commodities; Maps from the Ordnance Survey and historic maps from before 1800.
