Most of the early mediaeval legal texts were published within the leges series as part of the Monumenta Germaniae Historica . Scanned versions of all these works are now available on-line, although these are not searchable texts, simply images of the printed pages. Note that some of the most recent MGH editions are not available (e.g. the new Merovingian Diplomata volumes). Searchable CD-ROMS of the MGH have been produced by Brepols and are available networked in some academic libraries. Access to this database is also available over the net, but by subscription only.

Volume 1: L. Kéry, Canonical Collections of the Early Middle Ages (ca. 400-1140): A Bibliographical Guide to the Manuscripts and Literature (1999)
Volume 2: D. Jasper and H. Fuhrmann, Papal Letters in the Early Middle Ages (2001)
Volume 4: W. Hartmann and K. Pennington, The History of Byzantine and Eastern Canon Law to 1500 (2012) [one section is available on-line: Sources of the Greek Canon Law to the Quinisext Council (692): Councils and Church Fathers]
Volume 6: W. Hartmann and K. Pennington, The History of Medieval Canon Law in the Classical Period, 1140-1234 (2008)
There is also an on-line bio-bibliographical guide to canonists for the period 1140-1500.
Bibliography of writings of the late Prof. Hubert Mordek (d. 17 March 2006), noted especially for his work on the Vetus Gallica and the Carolingian Capitularies. His contributions to volume 3 of the History of Medieval Canon Law are yet to be published.
Carolingian Canon Law project (CCL): This is producing a searchable, electronic rendition of major works of Carolingian canon law, in a presentation that shows their relation to other works of canon law used by Carolingian jurists.
Pseudo-Isidorian Decretals (or False Decretals): a detailed web-site devoted to this ninth century compilation and its sources, which includes full text of the three Books plus the Capitula Angilramni and the Collectio Danieliana .
Benedict Levita's False Decretals : this mid-ninth century collection, closely related to Pseudo-Isidore, is here published in a new electronic edition, the product of a project led by Profs. Wilfried Hartmann and Gerhard Schmitz at Tübingen. The site also includes full details of manuscripts (including a recently identified ninth-century fragment of Book III now in the Beinecke Library), and texts or discussions of other related materials, which were either sources of or drew on the Decretals (e.g. Collectio Hispana Gallica Augustodunensis (Vat. lat. 1341) and the Summa de Ordine Ecclesiastico ).
Ivo of Chartres : on-line versions of his Collectio Tripartita, Decretum and Panormia, being the work of Bruce Brasington, Martin Brett and Przemyslaw Nowak.
Decretum of Gratian : a scanned version of Friedberg's 1879 edition.
Initia Operum Iuris Canonici Medii Aev i: Giovanna Murano's list of Canon law incipits (from Prof. Dolezalek's Leipzig site).

The main legal texts relating to the Visigothic kingdom can be read on-line in the scanned volumes of the Monumenta Germaniae Historica. The principal omission is the Breviary of Alaric (or Lex Romana Visigothorum ) of AD506, an edition of which was planned but never published. The Projet Volterra is planning a digital Breviary, of which Book 1 of the Pauli Sententiae is now available. Otherwise, the standard edition of that work remains that of G. Hänel from 1849 (repr. 1962 and 2004), which is now available on-line as a pdf. Some parts of the Breviary are available separately: thus the Epitome of Gaius (also on a second site), the interpretationes to the Sententiae Pauli, and the extracts from the Gregorian and Hermogenian Codes. The appendices found in some manuscripts are also available. A scanned manuscript version from St. Gall (Cod. Sang. 731; copied in Lyon in AD793) is available on-line at CSEG. Also available on-line is S.P. Scott's English translation (1909) of the Lex Visigothorum (Liber Iudiciorum). Note that his version does not reflect the different editions of that work as presented in MGH. We have made available on-line the Fragmenta Gaudenziana , a set of chapters apparently reflecting Visigothic law, preserved in the 10th century compilation known as the Collectio Gaudenziana.
Isidore of Seville (d. 636): his account of Roman law can be found in Book V of his Etymologiae (Origines). Note: Isidore of Seville is now regarded as patron saint of the internet and modern IT.
The main survival from Ostrogothic rule are the Variae of Cassiodorus, containing a great deal of his official pronouncements written for Theoderic and Athalaric. The other surviving legal text is the so-called Edict of Theoderic. The on-line text is taken from Bluhme's edition for the MGH. Although its attribution to Italy c.500 is now widely accepted, there is also the view, championed by G. Vismara, that it should be attributed to the Visigothic kingdom in the mid-5th century.
The Burgundian Code (Liber Constitutionum) and the Lex Romana Burgundionum (also known as the Liber Papiani Responsorum) are both available in the Monumenta Germaniae Historica scanned versions (each existing in two editions: one by Bluhme from the Leges in folio series vol. 3 and the other by de Salis in the Leges Nationum Germanarum series 2.1), but the Lex Romana Burgundionum (in the de Salis edition) is available on-line on the Koptev Roman law sites (Russia and Grenoble).
