These essays were published in Analecta OFM Cap 94(1975) in a special issue (number 5). Originally in various languages, Br. Ignatius McCormick OFM Cap made these translations. They were published in book form in 1983.

I have made a separate PDF file of each essay, since the PDF files are so very large! until I can convert the pdf into text files.
