Help In Locating Some Resources

Friends, I am attempting to locate the following in Melanchthon’s Opera Omnia:

  • Lamentations
  • Malachi
  • Galatians
  • Philippians
  • Titus

Has anyone a link to a pdf? I’ve searched Post-Reformation Digital Library​ with no luck and E-Rara as well.  Thanks for any tips.
