Early English Laws to quote from their website "is a project to publish online and in print new editions and translations of all English legal codes, edicts, and treatises produced up to the time of Magna Carta 1215" and "Early English Laws will provide not only the now standard editions of English legal texts by Felix Liebermann and William Stubbs, but also new editions, translations, and commentary for over 150 individual texts. These texts range chronologically from Æthelberht of Kent’s code (c. 600) to the issuance of Magna Carta in 1215, and include all non-narrative and non-administrative legal records. Some of them have never been edited."
