Johns(t)on pubs by Harry F. Johnston

I am interested in finding copies or sources for four Johnston documents by Harry Ferris Johnston.1.The JohnstonFamily. 2.Johnstons of Annandale, Dumfriesshire, Scotland and Eastern Pennsylvania3. Johnston Genealogy 4.Johnston Family of Eastern Pennsylvania.

In addition, most of these were originally published in a magazine Your Ancestors: a national magazine of genealogy and family history.So if anyone knows a library that will copy these periodicals, pls. let me know

Many thanks
