Additions, corrections, suggestions welcome: padraic.moran@universityofgalway.ie.

The list was compiled initially from the following sources (principally CLA and Bischoff in the first instance):

• J.J.G. Alexander, Insular manuscripts, 6th to the 9th century (London, 1978).
• Jacopo Bisagni, A Descriptive Handlist of Breton Manuscripts, c. AD 780–1100 (with contributions by Sarah Corrigan).
• Bernhard Bischoff, Südostdeutschen Schreibschulen und Bibliotheken in der Karolingerzeit, 2 vols (Wiesbaden, 1940–1980).
• Bernhard Bischoff, Katalog der festländischen Handschriften des neunten Jahrhunderts, 3 vols (Wiesbaden, 1998–2014).
• Dagmar Bronner, Verzeichnis altirischen Glossen (Marburg, 2013) [published in PDF].
• Foundations of Irish Culture online catalogue (c. 2014).
• E. A. Lowe, Codices Latini Antiquiores, 12 vols (Oxford, 1934–1971), digitised and updated at Early Latin Manuscripts.
• Patrick McGurk, Gospel Books and Early Latin Manuscripts (London, 1961).

Content still to add (July 2022):

• Further bibliographical information.
• Insular manuscripts of unspecified origin from CLA and Bischoff.
• Manuscripts for early transmission of Hiberno-Latin texts.
• References to Donnchadh Ó Corráin, Clavis Litterarum Hibernensium, 3 vols (Turnhout, 2017).

Interface changes planned:

• More refined search options.
• Map showing places of origin (probably by region).
• Various visualisations are planned, but will require some experimentation.
