The biblicalstudies.org.uk website now hosts over 950 public domain articles from the old series of the Journal of Theological Studies. All of these are now available for free download in pdf. Digitising them has taken some time as it was first necessary to find the date of decease of each author. Those articles whose authors died before 1945 are now considered Public domain, plus anonymous articles published before 1945. I hope that they prove of interest.
