The Society of Biblical Literature has just launched a new Texts and Resources page for members that provides access to PDFs and online versions of the Biblia Hebraica Stuttgartensia (BHS), the UBS Greek New Testament (UBS4), the Rahlf’s edition of the Septuagint, and the Biblia Sacra luxta Vulgatam. Here is the page’s description:
The decades-long commitment of the German Bible Society has produced the staples that have nourished generations of biblical scholars and translators. The booklet Textual Research on the Bible highlights this work. Through a partnership with the German Bible Society, the reading texts (upper texts, without critical apparatus) of four editions are available to SBL members in several formats for download and personal use.
The PDFs of the full documents are quite large, but you can download one book at a time, or use the online version to copy and paste text into other applications. Here’s a screenshot of the page for the BHS:
