Also included in this series are Skendzel's own writings, which form with bulk of Series I. Other copies of some of these writings are found throughout the collection, among the folders of research which related to that particular item. These writings include individual and collected manuscripts, some in draft and some in published format. Skendzel wrote a few books which are represented in the collection, but most of the publications are periodical articles, ranging in date from 1952 to 1996.

Skendzel also included with the items he actually authors those translations which he did of the writings of others. Eventually, the translations will be represented through a separate list, and in Series D, representing his facility with the language, but not his original thoughts. However, because Skendzel included these in several of his compilations and lists, the translations will often still be found in sources of Skendzel's work.
