"Selected Publications" is non-editable "boilerplate."  All my publications are listed here, and those underlined are downloadable  PDFs and/or have DOIs leading to PDFs.  I am adding downloadable articles daily at present.

Publications within the categories "Recent," "Articles in Scholarly Journals," "Chapters in Scholarly Books," and "Other Archived, Published Scholarly Writings" are in chronological order.  I believe none of the downloadable PDFs violate copyright, but please limit to one copy.
