I put United Service as a title into WorldCat, a website that finds items in nearby libraries. It immediately told me the universities in my city has this journal in their collection. I checked their catalog and it looks like they have the issue on microfilm. Tha's probably how most libraries will have it. WorldCat also said United Service is available online through ProQuest, a journal website. Access to journals on ProQuest is limited by subscription. Many large public libraries and most colleges and universities should have access. It looks like I might can get it through the New York Public Library. I will let you know.
