You can find most of these texts at the following sites:
New AdventChristian Classics Ethereal Library (also
here)
Both sites have strengths and weakenesses, the most significant IMO being that CCEL has much better notes and introductory material, while New Advent is easier to read and navigate through. If you can't find a text on those sites, Google will probably bring it up somewhere.
