An email to the Textual Criticism list from James Snapp is worth sharing hither and yon:

I've been delving into the Old Latin and early Vulgate evidence, and found some good (or at least good-looking) online resources. Instead of links, here are key-words to take you to them (at Google Books or Archive.org or both), with descriptions of what you will find.

Wordsworth White Novum Testamentum Latine: several volumes of WW's works on the Old Latin and Vulgate.

Abbott par palimpsestorum dublinensium: T. K. Abbott's presentation of the Greek Codex Z (presented in printed uncials to replicate the arrangement of text on the MS-pages), with two pages from Old Latin Codex Palatinus (containing Matthew 13:13-23) as an appendix.

Lawlor Chapters Book Mulling: "Chapters on the Book of Mulling," a nice review of the Book of Mulling with plenty of information about other Insular (Irish) Gospels-MSS.

John Stuart Book of Deer: the introduction tells you more than you will ever need to know about the background of the Book of Deer. The text is presented, with numerous Plates.

Hopkins-James Celtic Gospels: an excellent introduction to the Old Latin and early Vulgate materials in general, and to the St. Teilo/Chad Gospels in particular.

Lindisfarne Rushworth: a two-volume transcription of the contents of the Lindisfarne Gospels and the Rushworth Gospels.

Abbott Evangeliorum Antehieronymiana: T. K. Abbott's not-entirely-reliable but still serviceable collation of Codex Ussheriani, Codex Amiatinus, the Book of Kells, and the Book of Durrow.

Sullivan Book of Kells: a nice profile of the Book of Kells, with Plates in full color.

Buchanan Corbeiensis: an introduction to Codex Corbeiensis (ff2), with a transcription formatted to approximate the appearance of the text on the MS-pages.

Belsheim Codex Colbertinus: a no-frills transcription.

Also, if you have a high-speed internet connection, you should be able to view the "Turning the Pages" presentation of selected pages from the Lindisfarne Gospels at the British Library website, and the St. Chad Gospels (also called the St. Teilo Gospels) at the website of Lichfield Cathedral.

Also, some links to standard works on the Vulgate and OL are at Michael Marlowe's Bible-researcher site.

Also, if you go to the Mandragore website, if you type "Latin 9389" into the "Cote" box, you can view some pages from the Echternach Gospels.

Remember to type carefully; the search-box at Google Books can be rather unforgiving, and the search-box at Archive.org is even more so.
