Cite it as You Get It
Fortunately my librarian was able to quickly and easily obtain copies of the articles. Unfortunately the library supplying the material to me did not write an issue date on my copy [nor was it on the newspaper itself]. I was lucky that the article request form was sent to me along with the articles and I was able to determine the date of each reference. But always make certain you have dates and other relevant sourcing information for any copies of materials you make.
And don't write in green ink. It doesn't always copy or scan well ;-)
