Introducing MEMSO 4.5

TannerRitchie Publishing's Medieval and Early Modern Sources Online is an essential resource for the study of Britain and its place in the world c. 1000-1850.

Essential books and manuscripts

Bringing together the key sources from English, Irish, Scottish and Colonial history with original manuscripts and the latest web technologies, MEMSO has established itself as an indispensible online database for universities, researchers and libraries around the world.

The MEMSO Home Page

MEMSO's catalogue caters to a variety of academic disciplines and research specialisms. Whether your field is history, English or law, or your focus is political, ecclesiastical, social or economic, you will find relevant material in MEMSO.


Every week, new books or manuscripts are added to MEMSO. Subscribers can request specific titles and series they would like to have added.

Request books

One of the things that makes MEMSO so unique and so popular is the ability of our clients to recommend specific books and series that they would like to see in MEMSO. As MEMSO grows it is shaped to the needs of our subscribers.


Our printed sources are complemented by a growing collection of original manuscript images, including large collections of State Papers from the UK National Archives in Kew, London.


High definition images are downloaded, opened and arranged for easy viewing. Many manuscripts have never been published in printed form, while others are linked to the calendared versions in the printed State Papers.

MEMSO is enormously configurable, designed to replicate a historian's desktop, where many different sources and reference materials can be used at the same time.
