Join your local library. There should be copies of recent "Newsweek" articles on a shelf. Your library might have magazines in different formats. Some public libraries have their older magazine and journal articles bound by month and placed on book shelves in chronological order. Other public libraries pay for subscription databases where you should find "Newsweek" articles. For example, the homepage of the Louisville Free Public Library has a link to "Research Tools." Click on that link to see "Magazines & Journals." Select "InfoTrac OneFile."
Go to your university library. If you are not affiliated with a university, you will be allowed to use some of their print resources, but not their expensive, online sources. Check your university for policies on this matter. Indiana University, for example, has "Newsweek" articles from 1933 to 2010. After you find the articles you want, take the bound volumes to a photocopier.
Find a friend with access to a university's electronic resources. For example, Indiana University has 16 subscription databases with runs from 1975 to the present. The databases cover different topics, including business, academic, health and government. Some of the databases have full text searching with access to articles. Others show only abstracts and indices; some show pictures, others don't.
Remember that university and public libraries have microforms, such as microfiche and microfilm, containing older newspaper and magazine articles. The microfiche or microfilm has to be loaded into a machine to be read. You might be able to make copies at the machine.
