Textual criticism (and higher criticism) of the Bible is an ongoing field, perhaps just as strong now as it was in the 19th century. The Editio Critica Maior of the New Testament is an ongoing project. For competing theoretical work, see the work of Robinson and Pierpoint, who favour the Majority Text. For the Old Testament, there are the Oxford Hebrew Bible, Biblia Hebraica Quinta, and the Hebrew University Bible projects. For the Septuagint, there is the Göttingen Septuagint. There are many academic journals that deal with Biblical studies in general and textual criticism in particular. For active journals, see Journal of Theological Studies, published by Oxford University; Journal for the Study of the New Testament and Journal for the Study of the Old Testament published by Sage; Vetus Testamentum, Novum Testamentum and Biblical Interpretation by Brill; and New Testament Studies by Cambridge University. All of these are right in the academic mainstream.
