I am a bit late on this update but sometime ago, Larry Hurtado (Emeritus New College, University of Edinburgh) wrote a blog highlighting a peer reviewed journal for textual criticism that is completely online. I agree with Professor Hurtado that all journals need to be going to an online format. One benefit of this would valuable resources to research students at the many institutions with smaller endowments and smaller libraries.
The journal’s name is TC: A Journal of Biblical Textual Criticism is devoted to research in both Old and New Testaments and can be accessed here.
As a side note, I will be adding this and other online journals to the resource page for easy access.
