The Polar and Maritime History Research series contains PDF files of some of Stein's published research in polar and maritime history. The majority of writings in this series are biographical articles on 19th and early 20th century polar expeditionary members who received medals and similar awards for their work. These articles typically focus on the achievements or unique contributions of individuals in the context of international polar exploration activities happening at the time. Articles that more broadly cover the history of polar exploration, with a particular focus on medals awarded by various countries, are also included.

Materials in this series date from 2007-2020; these dates reflect the dates the digital files were last updated, which is also the date Stein last made corrections and additions to the document, sometimes after the original publication date. Titles indicate where each article was first published, as well as the date of original publication, noted in parentheses. The series is arranged chronologically based on the date of original publication. Articles that were published in the same year are arranged chronologically based on the date Stein last edited those files.

Materials are arranged chronologically. Dates reflect the last date edits were made to the work, which is the same date the digital file was created. Materials in this series were published in the same year the file was created.
