The listing for this product has an estimated 58 volumes and 14,000+ pages. But there seems to be little interest. Check out what the listing says:
"Calvin's publications, letters, tracts, and commentaries have seen continuous publication and reprinting for the past five centuries—and now you can have his sermons and lectures, too.
These sermons, most of which were preached originally in French, are archetypical of his lasting theology. Sermons on justification, Paul’s letters, and “matters very useful to our times” exemplify this in profound ways. Beyond this, his sermons and lectures on Old Testament books, the gospels, and the life and second coming of Jesus, give you unique insight to his unparalleled legacy."
Then:
"The following list of sermons includes only those works that are previously untranslated, and have so far only been accessible to specialists in the field. Other sermons of John Calvin—including his famous sermons on Genesis, Acts, and the Ten Commandments—will be included, but we have not yet determined whether they need re-translating or whether existing translations are adequate. This product will include all of John Calvin’s surviving sermons, even those not listed below. Keep checking back—we’ll update this page as more details become available."
