Internet Medieval History Sourcebook
The Internet Medieval Sourcebook is useful primarily as a source for short extracts, derived from public domain sources or copy-permitted translations, to be used for teaching (particularly for medieval survey courses). Also included are some complete documents, notably saints’ lives, or links to the full documents. The editor states that the early aim was to include a wide range of texts which address elite governmental, legal, religious and economic concerns. The resources now also include a large selection of texts on women’s and gender history, Islamic and Byzantine history, Jewish history, and social history. The texts, again according to the editor’s own statement, vary in quality, and do not always represent the best or most modern translation.

Manuscripta Mediaevalia
Manuscripts of Lichfield Cathedral
The Manuscripts of Lichfield Cathedral Project presents digital surrogates and bibliography on two medieval manuscripts held in Lichfield Cathedral: the 9th-century St. Chad’s Gospels and the 15th-century Wycliffite New Testament. The project offers both standard and multispectral imaging of the manuscripts, alongside RTI, or Reflectance Transformation Imaging for selected openings from the books.
Manuscripts of the West Midlands
Manuscripts of the West Midlands is an online catalog of the vernacular manuscript books of the West Midlands from c. 1300 to 1475. Created by a team at the University of Birmingham (UK), the project presents catalog entries of around 150 manuscripts associated with the region. Catalog entries include information on the text contained within a manuscript in addition to the physical features of the manuscript and its shelfmark at the institution of which it is a part. Users may find lists of manuscripts by repository, title, people, and bindings. There is also a keyword search function as well as a means to search by IMEV number.
Mapping Mandeville Project
The 14th century travel book and geography, The Travels of Sir John Mandeville provides readers with a fantastical tale of a man’s (supposed) journey from England to the farthest edges of the world. Sir John, the books’ narrator, tells stories of the sanctity of the Holy Land, of the wickedness of distant pagans peoples, and amazing and monstrous races that inhabit the corners of the globe. Taken as a whole, Mandeville’s book offers a remarkable insight into medieval ideas about geography, and about the way that the world was put together.
This project seeks to combine Mandeville’s text with one of the largest and most famous of the mappaemundi — the Hereford Map — in an attempt to use the two media together to make them more individually comprehensible. Using a legible copy of the Hereford map, I have annotated numerous locations on the map that also appear in Mandeville’s text. Clicking on these locations will bring up relevant selections from the text, and allow views to both understand Mandeville’s text within its proper framework, and to explore the foreign geographies of the map with a guide.
Mapping Metaphor: Metaphor Map of Old English
Mapping Metaphor is a project hosted by the University of Glasgow and represents the portion of the Mapping Metaphor project devoted particularly to the study of Old English. Deriving its data from the Historical Thesaurus of the Oxford English Dictionary, the project aims to provide useful data and data visualizations that map words and their usage as metaphors in Old English. The project presents over 70,000 metaphorical words in several visual formats. Users can also see which metaphorical words pair most frequently with a variety of statistical analyses.
The project has several tutorials and glossaries that teach a user how to use the database. Though the data itself is not available for download, the project includes several modes of searching its findings.
MARGOT
From the project: “MARGOT is a long-term research project devoted to publishing fully searchable editions of either generally inaccessible texts from the French Middle Ages and the Early Modern period (the Ancien Régime) or of texts in connection with a specific project from the same time period.”
MARGOT contains a number of other DH projects, including CANTUS, a database of medieval chant, French Women Writers, The Campsey Project, and Reading the Roman de la Rose in Text and Images, among others.

Matthew Paris’s Clickable Map: An Interactive Claudius Map
“This project presents an annotated copy of Matthew Paris’s c. 1250 map of Britain (BL Cotton MS Claudius D VI), made using Omeka’s Neatline extension.”
The annotated map is clickable with annotations that include text, images from medieval manuscripts, and sometimes modern photographs of locations depicted in Paris’s maps.
Measuring Polyphony
Measuring Polyphony is an ongoing project by researchers at Brandeis University and McGill University to digitally transcribe and notate polyphonic musical texts from manuscripts of the 13th and 14th centuries. As of 2020, the project presents around fifty musical pieces and has plans for growth. Currently, most of the transcribed musical texts are in Latin or French. Each entry presents musical texts in medieval mensural and modern notations. For some entries, the project presents manuscript images in IIIF format to compare against the marked-up scores. Pieces also include audio recordings of their performance in addition to downloadable data for each piece in MEI and PDF format.
Measuring Polyphony is committed to open-source data and has made the encoding process clear. The project also makes available all of its data in XML and MEI format and also provides access to its software apparatus on GitHub.
Medieval Bestiary
This web site deals with any and all aspects of the general topic “animals in the Middle Ages”, though there is an emphasis on the manuscript tradition, particularly of the bestiaries, and mostly in western Europe. The subject is vast, so this a large site, with well over 3000 pages, and perhaps the best way to explore it is to just wander around. The various pages making up the site are extensively linked; any text appearing in this blue color is a link (except for that one!). You can also click the green arrows at the top and bottom of each page; these will take you from one section to the next, or to the next page in a series. If you get lost, click the 
button on any page to return to the table of contents. If you are interested in bestiary manuscripts, start wil the section on the manuscript families, which will link you to various other pages of interest. If you want to learn about a particular animal, start with the Beasts pages. If you are looking for something in particular, try the site search. For more help in navigating the site, click the green on any page.
Informal articles, opinionated reviews, and irreverent comments on the bestiary genre can be found in the bestiary blog, Chimaera.
Medieval Kingdom of Sicily Image Database: A Visual Resource of Historical Sites c. 1100 – c. 1450
This database and website is a virtual museum of images produced between the late 15th through mid-20th century that document the architectural monuments of South Italy (the medieval Kingdom of Sicily) and their decoration (pulpits, mosaics, pavements) prior to destruction and restoration. The images, often produced during the Grand Tour or by artists and architects of a study journey to South Italy, are vital sources of information about the siting and character of the highly significant architecture sponsored by the Norman, Hohenstaufen, and Angevin rulers prior to the devastation of earthquakes, volcanic eruptions, and particularly the Allied bombardment of World War II.
Medieval Londoners
Medieval Londoners introduces resources available for research about medieval London and its people, focusing not only on documentary and narrative sources in print, but also archaeological, visual, and cartographic sources that illuminate the physical and material world inhabited by medieval Londoners.
An important component of the website is the Medieval Londoners Database (MLD), which records the activities of London residents between c. 1100 and 1520, and is searchable by name, gender, citizenship status, location (ward, parish, and street if available), craft, occupation, civic office, and craft office, among other variables.
Medieval Nordic Text Archive
The Medieval Nordic Text Archive (Menota) is a digital repository for medieval texts from Nordic repositories. A user can navigate the repository in either English or Norwegian. A joint project among many libraries and universities across Scandinavia, Menota invites editors to submit medieval texts in the Nordic languages or Latin. All texts on the platform have been marked up in XML and users can select a variety of views, like diplomatic of facsimile. As of 2020, over 50 manuscripts have been digitally edited and the project is ongoing.
Beyond digital texts, the platform also provides a few translations of medieval texts, lexicographical resources, and links to some images of manuscripts in Nordic repositories. Menota makes its encoding practices clear in documents and handbooks available on the site. The XML of digital editions hosted on the platform are open-source and available for download.
