Project Gutenberg, first begun in the 1970s, aims to provide free access to reading materials via the internet. The project currently includes over 50,000 open-access works, covering multiple subjects and representative of many time periods. Some of the works will be of interest to medievalists; editions of the Divine Comedy can be found in Italian on the site, for example, and other works of potential interest, both primary and secondary, are certainly to be found within the large collection. However, both the search and browse functions are outdated given current search engines. Even given the large number of volumes included, medieval works are more sparse than one might desire for inclusion in the MDR.
The REGESTA IMPERII (RI) records all documented and historiographically documented activities of Roman-German kings and emperors from the Carolingians to Maximilian I (about 751-1519) and the popes of the early and early Middle Ages in the form of German-speaking regesta. The website is a portal for the Commission on the regesta imperii, including links to the RI Opac (bibliographical search engine), electronic publications (work in progress editions and data collections), and the searchable RI database (chronological entries relating to imperial history from the Carolingian to the fifteenth century, based on the 80+ published volumes).
From the creators: York’s Archbishops Registers Revealed provides free access to over 20,000 images of Registers produced by the Archbishops of York, 1225-1650, in addition to a growing searchable index of names, subjects, places and organisations. The registers are a valuable, and in many cases, unexploited source for ecclesiastical, political, social, local and family history – covering periods of war, famine, political strife and religious reformation in the Archdiocese of York and the wider Northern Province.
The site contains over 5000 entries cataloged and organized with subject headings, indexes, and searchable contents. The project also offers IIIF capability for its images.
