Teeline Shorthand
Although Teeline has evolved over the years, often resulting in the streamlining of its theory and the simplification of certain outlines, a list of known historical published works can be found here, in descending order, most recent first. The vast majority of the books are available for purchase through eBay, Amazon or AbeBooks.com, among other sites. You may also wish to try BookFinder.com, which is a particularly good site for finding used books, rare books, textbooks, new and/or out-of-print books.
